TV BROADCAST WAVE SIGNAL RADIO TRANSMITTER AND TV BROADCAST WAVE SIGNAL RADIO RECEIVER

摘要

PROBLEM TO BE SOLVED: To provide a TV broadcast wave signal redio transmitter by which TV broadcast wave signals can easily be turned into SHF wave transmission signals. SOLUTION: An AGC circuit 4 directly amplifiers UHF band broadcast transmission wave signals Fi. The frequency Fi a local oscillation frequency F1 are mixed by a frequency mixer 5a. An SHF band frequency Fo, obtained by frequency conversion, is amplified by an electrical power amplifier 6a and is outputted from an output terminal 7. The local oscillation frequency F1 is generated from the two of the frequency Fu, generated by a local oscillator 8a in UHF band and the generation frequency Fs of a local oscillator 8b in SHF band.
