3.2 MT250 DC/DC Power Supply
The MT250 uses a DC/DC converter. It provides a voltage of 28V to the fans and a voltage of 15V to the
exciter. In addition, it supplies a voltage of 28V to the driver (MDL30). Below, the technical specifications:
Vdc Input 20 up to 53 Vdc
Output 1 15 Vdc/1.5 A
Output 2 28 Vdc/3 A
3.3 FM Stereo Exciter
The exciter is a OME-1T model. The declared nominal RF output power is 1 Watt; this signal arrives to the
RF final stage through the RF protection circuit. All the input connections are arranged on the front panel.
(See the annex datasheet).
3.4 MT 250 RF Control Circuit
The RF input circuit has 3 main functions:
1) RF power control
2) RF protection
3) Measurement/status indication
RF Power Control. A pin diode attenuator manages the RF input power coming from the exciter (OME-1T).
This attenuator can be manually controlled by RT3 trimmer, in order to adjust the right output power. The
AGC control regulates the power, manually set, versus frequency and/or temperature changes.
Moreover, the input attenuator includes a soft start, activated at the switching on or after any RF protection
intervention.
When the MT250 works at a very high temperature and/or high reflected output power, a derating circuit
provides to decrease the output power in order to maintain the equipment on duty, even at low power.
RF Protection. A fast comparator switches when the output detected reflected power exceeds a pre-set
threshold. The regulation of this threshold is made by RT2 trimmer, adjusted in factory at a value of 40 Watt
reflected power. When the protection is switched on, the protection circuitry cuts the RF signal applied to
the final stage amplifier very quickly, in about 1 micro second.
Measurement/status indication. The two main measurements, FWD and REF power, are displayed by
two BAR LEDS. The MT300 status is indicated with 3 leds: RF nominal, RF fault, RF derating. The RF fault is
on when the output power is lower than 3 dB related to the nominal output power. If the power decreases
in derating conditions, the fault is off in all cases. The enable SW1 switch is on the front panel. It is possible
to operate on the enable using the contacts on the rear panel, too. The enable of the amplifier is realized
when the SW1 is on and the rear panel enable is closed.
8
WARNING: with enable off, there is no RF out but all the internal circuits are supplied (stand by condition).
So, switch off the mains before operating inside.
3.5 MT250 RF Amplifier
The RF amplifier section provides to amplify the RF signal coming from the RF control circuit.
It is composed by:
• MDL30 (Driver)
• 90 deg. 2 way hybrid splitter
• a pair of final stage amplifiers mounting SD2931-10 devices
• 90 deg. 2 way hybrid combiner
The MDL30 provides the first step of amplification of minimum 17dB gain in order to correctly drive the final
stages. It is composed by a stage operating in class AB. Below, the technical specifications:
VCC 28V
Idq 200 mA typ.
Frequency range FM ( 87.5-108 MHz )
Power Gain > 17 dB typ.
Output Power > 25 W
The 2way splitter is made by a 90 deg. Hybrid structure and provides to split in quadrature the input
signal. Below, the technical specifications:
Frequency 87.5 – 108 MHz
Input power 50W Max
Return Loss (S11) <-17 dB
Return Loss (S22 ed S33) <-15 dB
Isolation (S32) >15 dB
Insertion Loss (S21=S31) <0.6 dB
The final stage is an amplifier for FM signal operating in band II (87.5 – 108 MHz), with nominal output
power of 250 Watt CW.
Normally it works up to 280 Watt, in order to win the Insertion loss of the circuitry that follows the
amplifiers, as the Directional couplers and Low Pass Filter.
It is a balanced amplifier, including a pair of single end sections, each one using a high power MOSFET with
the input / output matching network printed on the pcb. The RF MOSFET‘s bias are integrated on this
printed circuit board. The polarization is in class B, with a 10 mA quiescent current per section. The two
sections are split and combined by 90 deg. hybrid.
VCC nominal 48V
IDC (@ Full Power) 10 A typ.
Idq 20 mA typ.
Frequency range FM ( 87.5-108 MHz )
Power Gain Typ. 16 dB
Output Power 280 W min

The 2 way Combiner is a 2 way in quadrature structure, and it provides to sum each two final stage
sections to have 250 W power at the common port. One unbalancing 50 Ohm resistor warranties the
isolation between the input ports, in order to maintain the Transmitter on duty, in case one of the final
stages will be on fault (- 6dB derating).
Below, the technical specifications:
Frequency 87.5 – 108 MHz
Power handling 400 W Max
Return Loss (S11) <18 dB
Return Loss (S22 ed S33) <18 dB
Isolation (S32) >18 dB
Insertion Loss (S21=S31) < 0.4 dB
3.6 Low Pass Filter and Directional Coupler Unit
The filter has a particular elliptic configuration; this configuration has been specifically chosen to guarantee
the values of the harmonic components levels.
In-band Insertion Loss <0.5 dB
Insertion Loss @ 175MHz >55 dB
In-band Return Loss <-20 dB
The directional coupler is a block composed by 2 directional couplers and a quarter wave delay line. Both
ports of each directional coupler are used. Two of them detect the reflected power, one detects the FWD
power and one is used as RF monitor. The function of the delay line is to have two reflected power signals
detected at 90° of electrical angle. In this way, it is possible to have a quite constant reflected power level
vs the phase angle of that signal. The RF monitor is connected to the front panel (RF monitor port) to have
0 dBm nominal signal.

6.0 Set up procedure
The MT250 is shipped in a wooden box. It can be removed by lifting them with the banding straps that are
provided. This equipment can operate independently, and, thanks to its standard mechanical frame (19
inches), it can be located in a rack.
The MT250 is supplied for 220Vac, +/- 15%, single phase at 50Hz or 60Hz operation but it can work for
110VAC single phase, because its AC/DC power supply is a full range model. The normal current draw is
approximately 2.6 amps for 220Vac operation, but, if supplied at 110Vac, the normal current is around 5.3
amps. It is installer’s care to correctly connect the three wires (line, N, GND) to the mains line. Before
switching the transmitter on, it is necessary to connect the output power connector to either a dummy load
or an antenna.
After this procedure, it is possible to turn the transmitter on. On the front panel, the mains led indicates the
status of the MT250. If it is on, the equipment has been correctly supplied. Through the enable switch,
always on the front panel, the transmitter reaches the maximum power. Other leds provide further
information on the MT250
- RF nominal (green): on if some RF output power appears
- Derating (yellow): on in two situations
- when the reflected power is higher than 10dB (the transmitter power output is warranted until
VSWR 2:1. If the VSWR is higher, the derating protection intervenes. It stabilise the output power at
a non-dangerous value for the amplifier)
- when the working temperature is too high (the temperature protection intervenes when the room
temperature is =45°. In this case, the output power is reduced of about 6dB)
- Fault (red): on if the transmitter has other faults (for example, input power without output power, with
the following fault on the RF amplifier or RF control circuit).
Balanced Amplifier Advantages
The choice of using two RF devices has been decided in order to improve the raggedness of the amplifier in
case of mismatched dummy load. Thanks to the 90 deg. hybrid isolation the amplifier stages are not
influenced by the operating condition changes of the load (antenna, filter, and so on…).
Moreover, the amplifier is more immune to the oscillations than one realised with only one RF device.
The two hybrid RF devices allow the amplifier to produce output power (-6 dB) even if one of them breaks
or damages. In case of a single device, its fault provokes the amplifier switching off and the complete
disappearance of output power.
