Pasternack, a leading provider of RF, microwave and millimeter wave products, has added an all new product line of voltage controlled oscillators covering 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 new voltage controlled oscillators, commonly referred to as VCOs, 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 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.

A comprehensive and growing portfolio of VCOs from Pasternack includes over 60 different models in true surface mount and coaxial packaged versions available from stock. Some 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.

“Pasternack’s vast selection of voltage controlled oscillator models offers designers considerable flexibility with popular package styles, performance and functionality, with frequency bands that range from 10 MHz to 11 GHz,” says Tim Galla, Active RF Components Product Manager at Pasternack. “Another benefit is the added assurance that all models are designed to meet MIL-STD-202 environmental test conditions which makes them highly reliable and can be used for a variety of applications under extreme exposure conditions.”
