Our lines of voltage controlled oscillator series, commonly referred to as VCOs, cover select bands from 10 MHz to 11 GHz in a variety of package options. This line of voltage controlled oscillators is most commonly deployed in applications such as phase locked loops, frequency synthesizers, electronic jamming equipment and function generators.

Pasternack’s voltage controlled oscillator products are a type of oscillator where the frequency of the output signal can be varied by adjusting the amplitude of the input tuning voltage. The VCO performance characteristics play a critical role in overall system performance. Unlike oscillators with a single fixed frequency, VCOs have a range of frequencies making them desirable with designers.

Our comprehensive and growing portfolio of VCO part numbers include models in true surface mount and coaxial packaged versions available from stock. Some voltage controlled oscillator models have added features which include integrated buffer amplifiers and input modulation ports. Tuning voltages can range from 0 to 20 volts, output power ranges from 0 to +12.5 dBm, and all models have an operational temperature range covering -40°C to +85°C. These VCOs also boast exceptional phase noise performance as low as -125 dBc/Hz at 10 KHz offset. All designs are highly reliable and are designed to meet a series of MIL-STD-202 environmental test conditions, which include shock, vibration, and temperature cycle.
