A transistor RF power amplifier operating Class C is designed to produce 30 W output with a supply voltage of 50 V.
(a) If the efficiency of the stage is 70%, what is the average collector current
(b) Assuming high-level modulation, what is the impedance seen by the modulation transformer secondary
(c) What power output would be required from the audio stages for 100% modulation of the amplifier
(d) What is the maximum voltage that appears between the collector and emitter of the transistor
