WARNINGS AND CAUTIONS
WARNING
The Power Amplifier Module uses semiconductor devices containing Beryllium
Oxide. Dust from this oxide is toxic and, if inhaled or skin contact is made, can
be hazardous to health.
No danger can arise from normal handling, but no attempt should be made to
break open or tamper with these devices in any way.
These items should not be discarded with industrial or domestic waste.
WARNING
To avoid RF injury, do not touch the Antenna when the Transmitter is in use.
Do not operate transmitter with antenna disconnected – RF burn hazard.
WARNING
The weight of a fully assembled Base Station in the wall mount is approx 10kg.
Two people should be used to lift the unit in this form.
WARNING
When drilling walls, check first for any buried cables or pipes.
WARNING
Disconnect Mains Electricity before working on the unit with wall-mount or rack
power supplies open.
Caution
During disassembly and assembly, refer to the ‘Torque Settings’ section in this
manual.
Caution
Preparing the radio for alignment will erase from the radio all customer PMR and
Trunking configuration data (channel, signalling information etc). The only data
retained by the Alignment Tool is the factory alignment data for the radio (DAC
settings for TX power, front-end tuning etc).

3 DESCRIPTION
The Blade is a 1U high by 19” wide
rack-mountable unit containing two
SRM9000 sub-assemblies, a control
card, and a fan bulkhead which mates
with the angled front panel and MMI
card.
There is also provision for fitting a high
power amplifier or integrated power
supply option.
3.1 VENTILATION
Control Board
Receiver
Transmitter
High-power
Amplifier or
Integrated PSU
Option
In order to provide full-power
continuous operation in any
orientation and in a 1U envelope, the
Figure 3.1 - Layout of the Blade with the top lid
Blade uses forced air-cooling. A pair
removed
of fans draws air in from an air intake
located underneath the front lip of
the angled front panel. This air is
compressed by a baffle that directs
the airflow underneath the heatsink
of the SRM9000 sub assemblies. A
second pair of fans is used for the
high-power amplifier option if fitted.
Fans are located to maximise the cooling for the transmitting module. Air is exhausted
through a grilled area on the rear panel immediately below the electrical connectors.
Vent holes in the internal baffle allow a small amount of air to bleed diagonally through
the top section of the chassis to ensure that hot spots do not form on the component side
of the sub-assemblies.
The fans are mounted in a bulkhead located immediately behind the front panel. The front
panel, MMI board and fan bulkhead are separately assembled and removed from the unit
as sub-assemblies.
The fans, loudspeaker and indicator LEDs are all controlled from the MMI PCB that fits
into this sub-assembly. The fans are not only speed controlled to minimise noise and
wear, but their speed is also monitored to provide early warning of failure.
In normal operation, the fans are turned on to full speed to minimise any possibility of a
stall, the speed is then turned down based upon equipment temperature. Even if the
temperature is very low, fans are always kept running at a low speed. Temperature is
sensed from a Thermistor located on the underside of the control board. This Thermistor
protrudes into the airflow from the transmit PA module.
When installing the Blade it is important to ensure that adequate ventilation is provided
for each base station unit. A minimum free-area of 72cm is recommended per base
station at the inlet AND at the outlet. This should be increased if air has to be drawn
through ducts or has to be deflected around corners.
Noise and dust build up can be reduced by keeping cabling and other obstructions out of
the main airflows.
There are no dust filters fitted in this product. If it is to be used in very dirty environments,
then additional steps should be taken to prevent ingress of dust as this will affect thermal
performance. Filters should only be used in external cabinets if they can be regularly
maintained.
3.2 SRM9000 SUB-ASSEMBLY
The RF performance of this product is derived from a pair of SRM900 0 RF PCBs mounted
on a Heatsink sub-assembly that is designed to permit continuous operation at full power.
The sub-assembly also provides RF screening, so it is important that it is accurately
assembled and reassembled.
The sub-assembly has a plate attached to the rear edge with two quarter-turn fasteners
for rapid removal.
The unit is retained in the Blade chassis by the front edge of the Heatsink that inserts
underneath the fan baffle, the rear of the subassembly is held in place by the quick
release fasteners.
These units are electrically identical to SRM9000 and are also fully interchangeable in the
25W power group (the Transmit module is different for the 100W systems). Control is
provided via the 26-way ribbon connector. Power is supplied via the DB-15 connector and
RF signals are coupled to the BNC sockets with double-screened cables.

3.5.4 Ethernet
This is a 10/100 base-T RJ45 connection. This is a switch (not a NIC) configuration –
care should be taken to use the correct cable (crossover or straight-through) when
connecting to a network. The use of shielded cables is recommended, especially for VHF
installations. The two indicator LEDs, integrated into the connector, show 100Mbps
bandwidth detection and traffic activity. A third LED, on the Control Card shows if a
connection is present.

4.2.2.3 DSP
The DSP on the Xfin control card is a Blackfin device manufactured by Analog Devices; it
runs at speeds of up to 500 MHz. The DSP is responsible for all audio processing
including mixing, FFSK encoding/decoding, DTMF encoding/decoding, supervisory tone
generation, audio emphasis and speech processing for VOIP between Blades.
Booting
The DSP downloads the application code from the IXP Network Processor at start up and
runs the software entirely in internal memory.
RS232 Serial Interface (Rear RJ-45)
The rear of the Blade contains a standard RJ-45 Serial connection in order that an
engineer may connect a PC to the DSP via an RJ-45 to DB-9 cable. Debug commands
may then be issued to the DSP for diagnostic information.
CPLD Interface
Communications between the IXP Network Processor and the DSP are performed by
connecting the data bus on the IXP to the host interface (Lattice LC256V-75T100 CPLD)
connecting to the DSP. The IXP writes to the host interface, triggering a DMA on the DSP
to copy the data to a buffer. After a packet has been sent, the DMA on the DSP copies
data from an outgoing buffer to the host interface port that is read by the IXP. This
enables high-speed communications without impacting the performance of the DSP.
TECHNICAL DESCRIPTION
PAGE 33
4.2.2.4 Power
The control board requires a 12V 2000ma supply. Linear regulators are provided to
reduce the input voltage down to 10V and 5V for the audio circuits. The input voltage
supply is also regulated down to 3.3V for the digital logic via a switched mode power
supply. The 1.3V supply for the IXP processor core is generated by a regulator off the
3.3V rail. The 1.2V supply for the DSP core is generated by a diode (controlled by the
DSP) off the 3.3V rail.
4.2.2.5 IXP
Description
The main processor is an IXP42x processor manufactured by INTEL. It consists of a
central ARM based processor supported by separate network processor engines for
supporting the Ethernet and USB ports. The IXP runs the application code under
MontaVista Linux. The application code consists of Trunked Site Control, Inter-Blade
Communications, Site Configuration, Fan Control and the LCD menu system.
The network processor also provides support to the DSP. The IXP is connected to
external flash memory that stores the IXP software. Reset of the IXP is performed reset
circuitry monitoring voltage supplies.
Watchdog
The IXP processor has its own internal watchdog.
Fan Control
The IXP performs fan control via Maxim Fan Regulator devices, monitoring the
temperature of the airflow from the transmitter module using a thermistor (RT1). If the
temperature is too high or low, the speed of the fans is adjusted accordingly. Fans are not
allowed to stop during normal operation. Each fan generates a tachometer output
allowing software to detect a fan failure or potential failure by monitoring fan speed. If one
fan fails the speed of the second fan will be increased to compensate.
Analogue Outputs
Two analogue outputs are provided by a dual-channel Digital to Analogue Converter
(U41). They provide analogue outputs to the Facilities Connector to output, for example,
the RSSI level.
Analogue Inputs
The ADC (U56) has eight analogue inputs available, which are currently used to provide
voltage monitoring of the thermistor and the 12V unregulated supply, receive inputs from
the PA header and provide feedback of the analogue outputs.
Digital I/O
A set of shift registers (U10, U11, U15, U16 and U17) is controlled by the IXP via the
CPLD to provide digital I/O to the Facilities Connector as well as internal controls.
Ethernet interface
PAGE 34
TECHNICAL DESCRIPTION
XFIN-BLADE-SM
The IXP controls an LXT971 PHY chip (U20) that provides a 10/100 Base-T Ethernet
interface. The PHY is connected to an RJ-45 socket with built-in magnetics; the socket
also presents two external LEDs which are configured to indicate activity and 10/100
status.
RS232 Serial Interface (DB-9)
The rear of the Blade contains a standard 9-way Serial connection in order that a straight
through cable may be used to connect a PC to the IXP.
UART Serial Interfaces (Front Panel RJ-45)
The IXP presents a serial port interface to the RJ-45 port in the front panel.
4.2.2.6 CoDec
Audio received from either or both of the line ports and the PSTN interface is fed into a
chain of 3x AD73322L codecs (U52, U53 and U54) that is connected to the DSP via its
SPORT (Serial PORT) interface serial link.
The DSP performs audio signalling to the line equipment or patches the audio to the radio
module.
Handset audio is fed via a codec (U53) into the DSP allowing it to be mixed to line or the
radio modules under software control. Audio is also fed to the speaker on the front panel.
The codec contains built-in analogue gain adjustment under software control.
4.2.2.7 Audio Interface
General
External audio equipment is connected to either of the two independent audio ports which
are presented barriered on the RJ45 connectors, and un-barriered on the 37-way
Facilities Connector.
Two and Four Wire
The barriered connections are link selectable as either two or four wire. In two-wire mode
the balance of the hybrid can be set manually by moving LN18 (LN16 for port 2) to
position 2-3. If a test tone is generated to line, the reflected audio can be monitored on
TP57 (TP62 for port 2) and variable resistor R128 (R135 for port 2) can be adjusted to
give the minimum level.
At the time of configuration, the audio levels of the line ports must be set for optimal
performance. In line-to-air mode, it must be possible for a -10dBm signal to generate a
2.5kHz (full-scale) deviation. In loopback mode, an undistorted signal up to -10dBm
should be re-outputted with unity gain; this can be configured by inputting a -14.4dBm
signal (equivalent to 1.5kHz/60% deviation over air) into the line port and altering the gain
level until an equivalent -14.4dBm signal is seen at the output.
E&M
The control board contains opto-isolated digital inputs (U9, U14) and outputs (U8, U13).
In order to support local connections where an external bias voltage is not present, FuseTECHNICAL DESCRIPTION
PAGE 35
links F3 and F4 can be fitted to provide bias volts. This allows the unit to use DC
signalling.
4.2.2.8 PSTN Interface
A Clare DAA chip (U7) provides a PSTN interface. An audio channel links the telephone
port to a codec (U54).
At the time of configuration, the audio levels of the PSTN interface should be set for
optimal transmission and reception.

Ribbon Cable that carries analogue audio, digital audio and control signals.
Power connections are made via a 15-way, D-type connector and RF connections are
made via BNC sockets. RF connections are taken to the rear of the Blade via doublescreened cables terminated with female N-types.
4.3.2 Receiver
Refer to Figure 3.5.
4.3.2.1 Front-end Filters and Rx Front-end Amplifier
The receiver input signal from the antenna passes through the antenna filter comprising
L10, L11, L12 and associated tuning capacitors. With a transceiver module in receive
mode, diodes D3, D4 and D5 in the antenna switch are reverse biased allowing the
receiver input signal to be coupled through to the front-end with minimal loss. The overall
insertion loss of the antenna filter and switch is approximately 0.8dB.
Front-end selectivity is provided by varactor tuned bandpass filters at the input and output
of the RF amplifier.
Front-end tuning voltages are derived from the alignment data stored in the radio. The
DSP processes this data to optimise front-end tuning relative to the programmed channel
frequencies that may be changed at any time without re-aligning the radio.
To achieve the required varactor tuning range an arrangement of positive and negative
bias power supplies is used to provide a total bias across the varactors of up to 14.0VDC.
A fixed 2.5V positive bias derived from the 5.0V supply and voltage divider R425/426 is
applied to the cathodes of the varactor diodes. The negative bias supply originates at the
DSP/FPGA as a composite digital tuning signal (FE TUNE) containing the data for the
four front-end tuning values TUNE 1 to 4 for the particular channel frequency selected.
The level is dependent on channel frequency and tuning and varies between +0.1 and
+3.0V. This signal then passes through buffer U901A and level translator Q900 to Q903
where it is converted to a high level (-0.5 to -11.5V) negative equivalent of the original
signal.

The -12.0V rail of the level translator is generated by U300B/C with D304 to D306
providing the required voltage multiplier effect. The high level negative signal is then split
into the four individual front-end negative DC values under software control by multiplexer
U902 and associated storage capacitors C904 to C907 before being applied to the
anodes of the front-end tuning varactors.

TECHNICAL DESCRIPTION
XFIN-BLADE-SM
The RF front-end amplifier stage comprises a low-noise transistor amplifier (Q400), which
is compensated to maintain good linearity across the required frequency bands and
temperature range. This provides excellent intermodulation and blocking performance
across the full operating range. The gain of this stage is typically 17dB for both UHF and
VHF versions.
4.3.2.2 First Mixer and IF Section
The output of the last front-end bandpass filter is coupled into single balanced mixer
T400/D413 which converts the RF signal to an IF frequency of 45MHz.
The local oscillator injection level is typically +8dBm at T400 pin 1 with low side injection
used for UHF and high side for VHF. Following the mixer is IF amplifier Q401 which
provides approximately 15dB of gain and in association with its output circuitry presents
the required load conditions to the 4 pole 45MHz crystal filter Z401/402.
4.3.2.3 Quadrature Demodulator
Additional IF gain of approximately 30dB occurs at U401, which is a dedicated IF AGC
amplifier/Quadrature, Demodulator configured for single-ended input and output
operation.
The AGC voltage for U401 is derived from the RSSI function of the DSP via AUX CTL and
multiplexer U902. The onset of AGC operation occurs when RF input signal levels at the
antenna exceeds -90dBm. Conversion of the 45MHz IF signal to I and Q baseband
signals is carried out by the demodulator section of U401. The 90MHz local oscillator
signal is generated by VCO Q402 which is phase locked by the auxiliary PLL output of
U701 via feedback signal AUX LO2.
4.3.2.4 Receiver Audio Processing
All receiver audio processing and filtering functions are performed by the CODEC U800
under the control of the DSP.
The receiver I and Q analogue baseband signals are converted to digital signals by the
CODEC ADC before being applied to a series of digital filters which provide the final
stage of adjacent channel filtering, high pass and low pass filtering and mute noise
processing for narrow and wideband operation. The processed signals are then converted
to analogue audio signals by the CODEC DAC and are applied to conventional audio
amplifiers U803A/B and the speaker amplifier U5.
The speaker circuits are not used in the Blade. The carrier and signalling mute functions
are performed by Q810/811/813 under DSP control with additional receiver muting to
U803B being applied by U103C when the mobile is in transmit mode.
Flat audio (20Hz – 5.8kHz) is provided to S1-6 via amplifier U803A. De-emphasis is
performed on the Control Board.
Software functions are used to filter off signals below 300Hz and above 3kHz.
4.3.3 Transmitter
Refer to Figure 3.6.
TECHNICAL DESCRIPTION
PAGE 41
4.3.3.1 Drivers and PA Stages
The RF output level from the VCO buffer Q604 is typically +5dBm (UHF) and +8dBm
(VHF). TX buffer Q606 increases this level by approximately 3dB (UHF) and 11dB (VHF)
and also provides additional VCO isolation.
The following section of the TX buffer Q612 is controlled by the transmitter power control
loop and Q609. Q609 is normally saturated in transmit mode so there is no minimum gain
control applied to this stage. The gain of Q612 is typically 10dB (UHF) and 15dB (VHF)
but the output level is reduced by input and output resistive attenuators to limit the PA
driver input level to typically +20dBm. The gain of PA driver Q12 is controlled by the
power control loop to ensure that transmitter output power remains within defined limits.
The PA driver output level is typically +25dBm.
PA module U2 utilises three stages (UHF) and two stages (VHF) to achieve the required
final RF output power level of +44dBm (25 watts). Power output settings are derived from
alignment data stored in flash memory during the initial factory alignment. The DSP
processes this data to optimise the power output level relative to the programmed channel
frequencies which may be changed at any time without retuning the radio.
An active filter comprising Q14, 17,18 and 19 provides isolation to minimise power supply
noise at the PA. This is achieved by maintaining a voltage differential of approximately 1V
across Q14 and indirectly filtering its gate voltage. Q14 is switched on only during
transmit via R523 to minimise receiver power requirements.

4.3.3.2 Tx Power Control
Output power is stabilised by a power control feedback loop. L1, R54, a printed circuit
transmission line, D6 and associated components comprise the power detector with
Q3/10, U3 and associated components providing the power setting and control sections.
Forward and reverse power is sampled by the power detector and applied as a DC
voltage to the inverting input of comparator U3A. The TX PWR SET voltage, which is a
DC voltage proportional to the programmed TX power setting, is applied to the noninverting input of the comparator. PA module output level changes due to supply voltage,
load or temperature variations are detected and applied to the comparator which
proportionally adjusts the PA driver (Q12) supply, and therefore the PA drive level, via
Q10/Q3. High temperature protection is provided by Thermistor R452 which progressively
reduces the power level if the PA module temperature becomes excessive, approximately
86C case temperature. Q15 and Q16 provide for dual power control time constants
necessary for good power ramp and decay characteristics.
4.3.3.3 Antenna Changeover and Harmonic Filter
The antenna changeover circuit consisting of pin diodes D3/D4/D5 is switched by
Q4/Q8/Q11 and associated circuitry allowing the transmitter output to be coupled to the
antenna while providing isolation for the receiver input. With the transmitter switched on,
the diodes are forward biased allowing power to be coupled through to the antenna and
isolating the receiver by grounding its input at C28. The short circuit at the receiver input
is transformed to an effective open circuit at D3 by L13, which minimises transmitter
loading. With the transmitter switched off the diodes are reverse biased allowing the
receiver input signal to reach the receiver front-end with minimal loading and loss. The
harmonic rejection low pass filter comprises L10/11/12 and associated capacitors.
4.3.3.4 Transmitter Audio Processing
Microphone audio input signals of 40mV RMS, with a source impedance of 470 ohms, are
provided at the microphone input (AUD IN1) by the Control Board. Pre-emphasised flataudio, (300Hz – 3kHz; 20Hz – 3kHz; or 20Hz – 5.8kHz) is provided to the transmitter by
the Control Board via the 26-way ribbon cable. U108 is a control gate for the microphone
audio signals.
AUD IN2 is the external audio options and data input used by the Blade Control Board.
This is controlled by gate U107. Inverter Q20 ensures that the mic. audio is muted when
the data or audio options signals are active. The AUD IN2 input level and source
impedance is the same as the microphone input. Alternatively, the Blade can bypass the
audio input circuits by sending a digital audio stream to the transceiver module.
Q812 is a unity gain amplifier that provides buffering of the audio and data signals.
U103B provides CODEC input switching which selects either the receiver I signal or
transmitter audio/data signals depending on the TX/RX mode. All pre-emphasis, filtering,
compression and limiting processes for narrow and wideband operation are carried out in
the CODEC (U800) under the control of the DSP. The processed transmitter audio/data
from the CODEC output at VOUTL is applied to the VCO as a modulation signal with a
level of approximately 200mV P/P.

TECHNICAL DESCRIPTION
XFIN-BLADE-SM
4.3.4 Frequency Synthesis
4.3.4.1 General
Refer to Figure 3.7.
The SRM9000 frequency synthesiser consists of individual transmitter and receiver (local
oscillator) voltage controlled oscillators, loop filter, varactor negative bias generator,
reference oscillator and an integrated, dual phase locked loop device U701.
4.3.4.2 PLL
The PLL device contains two prescalers, programmable dividers and phase comparators
to provide a main and auxiliary PLL. The main PLL of U701 controls the frequency of the
TX/RX VCOs via Control Voltage outputs at pins 2 and 3 and VCO Feedback to pin 6.
The auxiliary PLL is used to control the receiver 90MHz second local oscillator via the
Control Voltage output at pin 17 and VCO Feedback to pin 15.
The PLL operation involves the division of the 14.4MHz reference oscillator frequency by
divider U710 and the internal divider of U701 down to a lower frequency which
corresponds to a sub-multiple of the radio channel spacing i.e. 6.25kHz for 12.5/25kHz
channel spacing or 5kHz for 20kHz channel spacing. The VCO frequency is sampled and
divided down to the same frequency after which it is phase compared to the reference.
Any error produces an offset to the Control Voltage output which is used to correct the
VCO frequency. A valid lock detect output is derived from pin 20 and is sampled by the
FPGA during transmit. If an unlocked signal is detected the radio will switch back to
receive mode.
4.3.4.3 VCO
The transmitter and receiver VCOs use low noise JFET transistors (Q600 RX, Q602 TX)
and inductors L602 (RX), L608 (TX) to generate the signals for the required band
coverage. Electronic tuning is provided by varactor diodes D600 to D608 with their control
voltages derived from the Loop Filter, PLL and Negative Bias Generator. VCO selection
and timing is controlled by the DSP via the RX and TX power supplies and applied
through switches Q601 (RX) and Q603 (TX). VCO buffer Q604/605 isolates the VCO from
load variations and active power supply filter Q615 minimises supply related noise. A PLL
feedback signal is sampled from the VCO buffer output via buffer Q607.
4.3.4.4 Negative Bias Generator and Loop Filter
A positive and negative varactor bias supply similar to the front-end varactor arrangement
has been used to achieve the required broadband tuning range of the VCOs. PLL device
U701 is programmed to deliver a fixed nominal +2.5V output from phase detector/charge
pump CPPF or CPP (selection depends on radio setup) regardless of the channel
frequency selected. This voltage is filtered to remove synthesiser noise and reference
products by loop filter C719/722/734 and R721/724/734. The resulting low noise voltage
is applied to the cathode side of the VCO varactor tuning diodes as a positive bias
voltage.
The negative bias supply originates as a positive DC voltage (0.1V to 3.0V) at the DAC
output of U701 (DOUT) with a level relative to the programmed state of the radio (e.g.
TECHNICAL DESCRIPTION
PAGE 45
channel frequency, TX/RX state). The voltage is converted to a high level negative supply
by VCO Varicap Negative Supply Q700 to Q703. The -17V rail of this supply is generated
by U300B/C with D304 to D307 providing the voltage multiplying effect needed to achieve
-17V. The output of the negative supply is applied directly to the VCO varactor anodes as
the negative tuning voltage VCAP BIAS.
4.3.4.5 Phase Modulator
The modulation path for audio, data and higher frequency CTCSS signals is via D609 and
its associated components in the TX VCO. The reference input to the PLL (FXTAL)
provides the low frequency modulation path in conjunction with phase modulator Q714 to
Q716. U711A is a low pass filter that provides 6dB per octave attenuation to frequencies
above approximately 180Hz. Modulation balance adjustment is carried out using a
CODEC generated 100Hz square wave applied to TX MOD1. A DAC output from the
Alignment Tool is applied to buffer U711B and ramp generator Q711 to Q713 via the
TUNE BAL line to adjust the low frequency modulation level.
4.3.4.6 Reference Oscillator
TCXO U700 determines the overall frequency stability and frequency setting of the radio.
The frequency setting is achieved by adjusting its ADJ voltage with the Alignment Tool. In
addition, the ADJ input is used in a frequency control loop with the receiver I and Q
signals to provide receiver AFC. U700 operates at 14.4MHz and is specified at ±2.0ppm
frequency stability over the temperature range –25C to +75C.

Figure 3.8 - VHF/UHF Control Block Diagram
4.3.5.1 DSP and FPGA
The Blade RF sub-assemblies operate under the control of a DSP (U102) and FPGA
(U106) combination which together with a number of other dedicated devices perform all
the operational and processing functions required by the radio. The FPGA is configured
by the DSP under software control to provide the following functions:
·
Channel set-up for operating frequency
·
Modulation processing and filtering
·
De-modulation processing and filtering
·
TX power output reference
·
Receiver front-end tuning
·
Serial communications with control board
·

4.3.5.2 DSP Clock Oscillator
The DSP is clocked by a 15.360MHz oscillator that consists of crystal X100 and an
internal DSP oscillator. Q100 forms a crystal switching circuit with C117 which when
activated by a command from the FPGA steers the oscillator away from potential
interfering frequencies.
4.3.6 RF Sub-Assembly Internal Memory
Memory consists of the internal DSP memory and an external 4MB non-volatile Flash
Memory U104. When power is off, program and data is retained in Flash Memory. At
power-on, a boot program downloads the DSP’s program from Flash Memory to its
internal RAM for faster program execution and access to data.
4.3.6.1 Multiplexer
U902 contains 2 separate 4-channel multiplexers providing a total of 8 independently
controlled analogue switches. Under software control, the multiplexers produce tuning
voltages from supplied data for the receiver front-end (TUNE 1 to 4), TX power setting
(TX PWR SET), receiver AGC (AGC-1), alert tone (A TONE) and FPGA ramp generator
(ADC REF).
Buffer U802B is fed with a composite digital tuning signal (AUX CTL) from the DSP/FPGA
containing the data for AGC, A TONE, ADC REF and TX PWR SET settings. The level is
dependent on channel frequency and tuning and varies between 0.1 to 3.0V. This signal
TECHNICAL DESCRIPTION
PAGE 49
is applied to one group of 4 analogue switches in U902 via a common input connected to
pin 13. The second group of 4 switches is fed with the receiver front-end tuning signal FE
TUNE (to provide outputs for TUNE 1 to 4) via the second common input at pin 3 as
described in the receiver front-end section.
The 2 groups of analogue switches are independently controlled by FPGA binary signals
MUX A0 and A1 and enable line MUXEN to output the required tuning voltages as a
series of pulses. These pulses are converted to steady state voltages by integration
capacitors C904 to 911 and C921 to 925.
4.3.7 RF Sub-Assembly Internal Power Supplies
4.3.7.1 Power On Function
This set of functionality is designed for normal use in a vehicle environment; hence much
of it is unused in this product.
The unregulated 13.8V DC input is routed directly to high current devices and is also
switched via FET Q350. The output from Q350 feeds three, low drop out series regulators
and associated switched and auxiliary supplies that along with a negative voltage
generator provide all the switched power requirements of the transceiver.
Q315/316/317 and U313 form a power on/off latch circuit that is activated by a pulse from
the control unit or microphone/handset via PWR ON or PWR OFF and controls the FET
power switch Q350. A PWR OFF operation requires the button to be held down for more
than 2 seconds. This is then sensed by the FPGA via the PWR SENSE line that turns the
radio off by placing a positive pulse on the PWR OFF line thereby resetting U313B.

4.4 ANTENNA REQUIREMENTS
The antenna connections on the Blade are provided with 50W female N-type sockets.
These should be tested, by use of a suitable test set, e.g. Anritsu/Wiltron S331A, for good
VSWR (1.5:1 or better) at the Tx and Rx frequencies prior to use.
Mating connectors should be galvanically compatible with nickel outer and gold centre pin
to minimise passive intermodulation.
A minimum of 85dB transmit-receive isolation should be provided by the antenna system
and associated filters.
4.5 POWER SUPPLIES
For type approval reasons, this product should not be operated with un-approved
supplies.
The switch mode supplies used in the wall mount and rack mount ancillaries are able to
accept main AC in the range of 100 to 240 V, 50 or 60Hz. The output from the switched
mode power supply to the Blade is +13.6VDC.
Pin 3 on the D-type Power Connector provides protective earthing on the equipment. This
should be connected using heavy duty Green/Yellow earthing wire, capacity greater than
mains feed to equipment, as few bends as possible and an appropriate eyelet tag.
Mains protective Earth should be checked for low impedance (<0.3W).
The equipment must be installed so that the IEC connector for the Wall or Rack Mount
can be easily removed and/or the power socket should be readily accessible.
All mains wiring must comply with local wiring regulations.
4.6 CONFIGURATION
Configuration is provided via file download. This is performed via the XBMT Programmer
using a PC connected to the Xfin Control card via its Ethernet port. Files are then stored
in the product in non-volatile memory.
Editing of parameters on a live base station is also possible with a connected PC.
4.7 ADJUSTMENT AND ALIGNMENT
The two RF modules within this product are based upon the RF card of an SRM900 0
mobile. The set up and alignment procedures for SRM9000 should be followed. In the
event of a level-3 repair being required, refer to the SRM9000 Service Manual (TSDSRM9000-SM) [1].
There are no user adjustments to be made in normal use.

C. RADIO FREQUENCY HAZARD INFORMATION
RF Hazard Test conducted by EMC Technologies (NZ) Ltd - test report no. 70232.1.
Report date: 26 March 2007.
Test report is as follows:
As per Section 1.1310 and Section 2.1091 certification of this transmitter is sought
using the Controlled / Occupational exposure limits as detailed in OST/OET Bulletin
Number 65 as a power of 100 watts is to be used in a fixed environment.
Calculations have been made using the General Public/Uncontrolled Exposure limits.
Minimum safe distances have been calculated below.
Power density, W/m2 = E2/3770
- Occupational / Controlled Exposure limit will be 1.46 mW/cm
(f/300 = 440 MHz/300)
- General Population / Uncontrolled exposure limit will be 0.29 mW/cm
(f/1500 = 440 MHz/1500)
The minimum distance from the antenna at which the MPE is met is calculated from the
equation relating field strength in V/m, transmit power in watts, transmit antenna gain,
transmitter duty cycle and separation distance in metres:
E, V/m = (√ (30 * P * G)) / d
Controlled Uncontrolled
E = 1.46 mW/cm2 = E2/3770
E= √1.46*3770
E = 74.2 V/m
E = 0.29 mW/cm2 = E2/3770
E= √0.29*3770
E = 33.1 V/m
The rated maximum transmitter power = 100.0 watts.
Transmitter operated using a quarter wave whip antenna with a gain of 2.15 dBi (1.64).
Controlled Uncontrolled
d = √ (30 * P * G*DC) / E
d = √ (30 * 100.0 * 1.64) / 74.2
d = 0.94 metres or 94 cm
d = √ (30 * 25.0 * 1.64) / 33.1
d = 2.11 metres or 211 cm
Result: Complies
