Broadband UHF Power Amplifier For TV Transposers 3W
A broadband RF power amplifier design is presented, suitable for application in TV transposers, operating in UHF band IV and V(470 - 860) MHz, with simple printed circuit board.
The Rf power amplifier design is based on a BLW898 bipolar transistor. Typical results at the recommended class-A biaspoint (25 V/1.1 A) for the total module include a 3-tone IMD level of -64 dB (fvision = -8 dB, fsideband = -16 dB and fsound = -10 dB) and an average gain of 10.5 dB at 3 W peak-sync output power in the (470 - 860) MHz frequency range.
