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 MT250 RF Monitor Left Rigth Ext/MPX SCA/RDS AUX ENABLE LED

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 Output 1 Output 2 3.3 FM Stereo Exciter 20 up to 53 Vdc 15 Vdc/1.5 A 28 Vdc/3 A 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. 7 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.

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 MOSFETs 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 IDC (@ Full Power) Idq Frequency range Power Gain Output Power 48V 10 A typ. 20 mA typ.

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).

<-20 dB 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. 9 4.0 MT250 Technical Specifications Environmental Storage Temperature:

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 installers 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. 13 14 OME-1T 1W - FM Stereo Transmitter 1W FM Broadcast Exciter for Mono / Stereo Operations
