The MT300 RF Module, Final Power Stage The final RF power section on MT300 transmitter is composed by: 1. RF Driver: model MDL30. 2. 90 deg. 2-way hybrid splitter. 3. A pair of final stage amplifiers mounting SD2931- 10 devices. 4. Second; 90 deg. 2-way hybrid splitter. The MDL30 provides the first step of amplification of minimum 17dB gain in order to correctly drive the final stage. It is composed by a stage operating in class AB. Below the technical specifications: Vcc 28 volts Idq 200mA typ. Frequency range 87.5 – 108 MHz Power Gain >17dB typ. Output Power >25 W The 2-way splitter is made by a 90 deg. Hybrid structure and provides to split in quadrature the input signal. Below the technical specifications: Frequency Range 87.5 – 108 MHz Input Power 50 W max. Return Loss, (s11) <17dB Return Loss, (s22 and s33) <15dB Isolation, (s32) >15dB Insertion Loss, (s21=s31) <0.6dB The final stage is an amplifier for FM Broadcast band, (87.5Mhz to 108MHz), with nominal output power or 300 watt CW, that also can operate at 390 watt CW. Normally it works compensating the losses of the passive and linear circuitry that follows the amplifier, the directional coupler and the low pass filter. The necessary typical pre-gain compensation is about 0.9dB. This means the RF amplifier output runs at 370 watt for a nominal 300 watt at the output connector. The amplifier topology is a balanced amplifier, including a pair of single ended sections, each one using a high power MOSFET with the input/output matching network printed on the PCB. The choice of using two RF devices has been decided in order to improve the raggedness of the amplifier in case of strong mismatched load at the output network. Thanks to the 90 deg. Hybrid isolation, the amplifier stages are not influenced by operational conditions changes of the load (antenna, filter, transmission line and so on). Moreover, the amplifier is more stable and because of that more immune to the self-oscillations. The two hybrid RF devices allow the amplifier to produce output power (-6dB) even if one of them breaks or damages. Below the technical specifications: VCC nominal 48V IDC (@ Full Power) 11A typ. Idq 180Ma typ. Frequency Range 87.5 – 108 MHz. Power Gain 18dB, typ. Output Power 280 w - 370 w. Polarization Class B The 2-way combiner is a quadrature structure, and it provides the sum of each two final stage sections to have the max RF power at the common port. One unbalanced 50 Ohm RF 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. Below the technical specifications: Frequency Range 87.5 – 108 MHz Power Handling 400 W Max. Return Loss, (s11) <-18dB Return Loss, (s22 and s33) <-18dB Isolation, (s32) >+18dB Insertion Loss, (s21=s31) <0.4dB The low pass filter has a particular elliptic configuration; this configuration has been chosen to guarantee the values of the harmonic components levels. Below the technical specifications: In band insertion loss <0.5dB Insertion loss @ 175Mhz >55dB In band Return Loss <-20dB 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 the one is used for RF monitor. The function of the delay line is to have the reflected power signal detected at 90 deg. of electrical angle. In this way, it is possible to have a constant reflected power level versus the phase angle of that signal. The RF monitor is connected to the front panel to have a 0dBm nominal signal. Below we can see a photo of the MT300 RF Module Amplifier

1.0 OVERVIEW MT300 is a 300 Watt FM Low Power Transmitter. It is very simple and easy to use. It is composed by a mechanical frame (19 inches std., 3 HU high and 500mm depth), an exciter (OME-1T), a RF section, which comprises a RF control board and an amplifier section, a directional coupler and a low pass filter, a display, a power supply with a AC/DC converter and a DC/DC converter. 2.0 BASIC BLOCK DIAGRAM OF MT300 The RF section part number is GR00232ASE.

It has a wide range with an input voltage of 85/265V and an output voltage of 48V. Below, the technical specifications: Nominal Output Voltage 48V Max Output Current 13A Max Output Power 624 Watt Efficiency 83% typ. Input Voltage Range 85-265VAC (47-63Hz) PFHC Built to meet EN61000-3-2 Power Factor(100/200VAC) (typ) 0.99/0.95 Output Voltage Range 43.2-52.8V Over Voltage Protection 55.2-64.8 3.2 MT300 DC/DC Power Supply The MT300 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 300 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 MT300 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. 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 MT300 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.

Normally it works up to 370 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, SD2932, with the input / output matching network printed on the pcb.
