ABSTRACT:
Signal modulation apparatus includes a PIN diode network which is fed a carrier signal from a carrier signal source and a modulation signal from modulating current output terminal which receives a modulation current directly from a temperature-compensated constant-current amplifier and a signal via a unity gain amplifier from a reference diode which is also fed from the constant-current amplifier which is adapted to receive a modulating signal.
