This RF power amplifier application works on UHF band frequency 440 Mhz and uses as UHF repeater power amplifier. Power amplifier out 30 watts (5 dB gain) use a single transistor 2SD1434.
For driving the amplifier use 10-14 watt input with output power range 30-45 watts. Please see datasheet sample design for 470 MHz (SD1434.pdf) and Amplifier Application Note produced by Hamtronics.
Other use of the power amplifier is for online covering broadcast (STL). If you use stereo encoder on exciter, so please use down converter with 340 MHz oscillator frequency direct to FM broadcast receiver.See more : FM Stereo Encoder - Power Amplifier - Audio Video Modulator
