2 FEATURES SUMMARY
2.1 GENERAL ARCHITECTURE
The Laird Transceiver consists of a UHF Receiver as well as a UHF Transmitter section that is controlled by a
digital subsection providing and processing protocol and control functions for the overall radio requirements.
The transceiver is intended to be powered using an externally provided 12VDC supply.
The overall current consumption @ 12VDC in RX mode is about 110mA.
The Transmit section was designed to provide a nominal output power of +27dBm into a 50 ohm load.
The overall current consumption for TX is an additional 450mA, resulting in a total current during TX of about
560mA.
The RF section is contained in a shielded enclosure that has openings for four 50ohm SMB connections:
1. ANT1 --- RX input 1
2. ANT2 --- RX input 2
3. ANT3 --- RX input 3
4. TX OUT
In addition to these there are openings for visual observation of the PLL Lock status, as well as two alignment
points, one adjusting the 2nd RX LO frequency and adjusting the RX Quadrature detector.
There is no need to trim the TX and the RX front end sections,
The following sections will contain a detailed description of the different circuit blocks pertaining to the
transceiver.
2.2 POWER SUPPLIES AND REGULATORS
A nominal external 12VDC is supplied to the assembly using P101 pin 7 (positive) and pin 10 (negative).
This input is directly fed to U113 (LT1961EMS8-5#PBF) and to U5004 (KA7809). The +5VDC output of U113 is
used to supply the digital section as well as the RX DATA buffer and shaping amplifiers and the modulation
active filter chain, this +5V supply voltage feeds also a 2.7V voltage regulator to supply the ADC reference
voltage for the CPU (U6001 – ADP160AUJZ-2.7).
The +9VDC output is used to feed the RF RX regulator MIC5216-5.0 (U4) which provides +5V to the synthesizer
and RX chain.
The +9V output is also used to supply regulator U52002 (KA7805) which is powering the TX Driver and PA stages.

Revision: A, Approved
2.3 Frequency Reference and Phase Locked Loop:
The overall RF system frequency reference is provided by a 14.4 MHz VCTCXO (designator Y4).
The synthesizer uses an external VCO (designator U6) that is tunable from 425 to 475 MHZ.
The nominal RF output level of the VCO is nominally between +2 and +6 dBm into 50 ohms.
The RF output of the VCO is subsequently split using resistive dividers into:
1. RF Sample input for the PLL
2. 1st RX Mixer LO input
3. TX signal input to the TX Amplifier chain.
2.4 Receiver Section:
The RF input to the Receive section is provide using one of the existing ANT1, 2, 3 input, these are selected using
signals provided by the Microcontroller (designator U5).
The received signal is the routed to a UHF SAW filter FL1 that has a width of about 20MHz and is centered in one
of the designated RX bands:
Low Band – 406 to 425 MHz
Mid Band – 425 to 447 MHz
High Band – 447 to 475 MHz
These filters are installed depending on the RX Band variants that are being used.
The Local Oscillator input is supplied by an output of the splitter mentioned above referring to the VCO.
The 21.4MHz mixer signal output is filtered using a crystal Filter (designator Y1), the BW of this filter is selected
depending on the product variant built (either a narrow or a wide band version).
After filtering the 21.4 MHz signal is routed to an FM IC that performs an additional frequency down-conversion
to 455kHz and provides a second mixer and 2nd LO oscillator using and externally supplied crystal (designator
Y2).
The FM IC SA605 (designator U2) additionally provides limiting IF gain and quadrature detection as well as
having outputs for RSSI monitoring besides the demodulated signal.
The second IF Filtering is provided using two 455kHz Ceramic Filters 455FU (455DU) (designators FL3 and FL4).
