CWWP10XXDE1VHF AMPLIFIER

1 -- Crescend Technologies -- Power Amplifiers P10-xxDE1-C5-001. Unit Description and User Manual. 1. General description. The power amplifier (PA) is nonlinear AB to C class unit that is intended for frequency (phase) modulated (manipulated) signals amplification. There is the fan for forced cooling, which starts rotating, when the sufficient RF signal is applied to the unit input, or when the heatsink inside temperature reaches +85ºC. The automatic power control loop keeps the output power at the rated level. It reduces this level, when the load VSWR is above 2, when the heatsink temperature exceeds +85ºC or under the outer control.

Schematic Description. RF Circuitry Description. RF signal, applied to the connector “RF IN”, proceeds via the attenuator ATT1 and the coax cable to the pad J1 of Pre-Amplifier Board. There is the attenuator ATT2 (R10...R12). The part of RF power at the output of ATT2 comes to the input detector D1. The main of RF signal passes 10 dB attenuator (R6, R7, R8, R13) and comes to the input of power amplifier U1. Amplified RF signal from the pad J2 of the Pre-Amplifier Board, comes to the pad J1 of the Final Stage Board. After 3.5 dB attenuator (RF1, R3) RF power distributes by the splitter Y1 evenly between two amplifying modules U31 and U51. Combined by Y2 signals go the pad J2 of the Final Stage Board, and then, to the pad J1 of the Output Board. There is the low-pass filter (L1...L3; C12...C15), needed for the harmonics suppression, at the way of RF signal, as well as directional couplers Y1 and Y2. These couplers together with detectors D1, D2 form DC voltage, proportional to the forwarded and reversed RF powers at the unit output. The unit output connector “RF OUT” is connected directly to the pad J3 of the Output Board. Keying Circuitry Description. 2 DC power supply voltage is applied to clamps “+/- 13.8V”. There is the power diode DR, which protects the unit against the polarity reversing. The power supply voltage comparator (Q1 in the Control Board) open the key Q2, if the power supply voltage is less than 16.0 V. Open Q2 delivers the supply voltage to the input power comparator U1. Immediately after DC voltage is applied to the unit, the fan self-test is performed: Q4 opens, opening the fan key Q7 for several seconds. When the voltage at the output of the input RF detector, coming to the pin J1-2 of the control board, exceeds 1.4 V, a high voltage at the output of U1 (pin U1/1) appears. Then: - Q5 and Q7 in the Control Board open, switching the cooling fan on; - the control circuits reference voltage, supported by D9 in the Control Board, appears. The right half of Q3 becomes closed, allowing the reference voltage to go to the circuits; - 9.5 VDC sets at the output of control/monitoring circuits voltage regulator (Q9, Q10) in the Control Board; - the bias voltage for RF amplifying modules U31 and U51 in the Final Stage Board appears. This voltage comes to the Pre-Amplifier Board, as well; - Q11 and Q21 in the Control Board become open, sending the monitoring signal “TX” and the voltage to by-pass or T/R switching relays, if this is necessary; - the local voltage regulator (Q5...Q9) is activated in the Pre-Amplifier Board, giving the supply voltage for the RF amplifying device U1; - with the bias voltage coming, key transistors Q32...Q34 and Q52...Q54 in the Final Stage Board open, passing the bias voltage to pins 2 of modules U31 and U41, and giving the supply voltages to comparators of the module current limiters (U32, U52). Power Control Circuitry Description. The voltages, proportional to the output forwarded and reversed power, come from pads J4, J6 of the Output Board via the connector J2 of the Control Board to some inputs of operational amplifiers (OA) set U2 in the Control Board. These voltages are levered, i.e., they become equal, when the load VSWR reaches the threshold value (~ 2.5). The threshold is setting by the resistor R12 in the Output Board. OA U2-A and U2-B together with D6 are selecting the maximum of forwarder and reversed voltages. The selected voltage comes to the inverting input of OA U3-A. The reference voltage from the potentiometer RP1 is applied to another input of U3-A. The bias voltage (for modules U31, U51 of the Final Stage Board) is formed at the emitter of Q16. D7 does not allow this voltage to be greater than 5V. When this voltage reaches its maximum, Q15 opens, and LED D8 goes on, indicating that the RF output power control loop is open. The voltage regulator in the Pre-Amplifier Board (Q5...Q8) is also th…
