描述 Description

SOR-M3 is a voltage regulator for GaAs Gunn diode base Gunn oscillators with capability to provide amplitude modulation (AM) or Frequency Modulation (FM). The voltage modulator is designed and manufactured to protect the Gunn oscillator from accidental over-voltage or reverse bias. The well-regulated and low-ripple output voltage supplied by this modulator also helps to reduce possible RF signal degradation and noise caused by bias voltage ripple or fluctuations when supplied by a low-quality DC power supply. If a signal between 0 to +5 Vdc or TTL is applied to AM input connector, the Gunn oscillator will be “turned-on” and “turned-off”, creating amplitude modulation (AM). If a signal between +5 and -5 V is applied to the FM input connector, the Gunn oscillator bias voltage will vary proportionately, causing the Gunn oscillator frequency to change accordingly, creating frequency modulation (FM).
