Voltage-control oscillator supports multiple frequency bands

Fairview Microwave has unveiled voltage-controlled oscillators (VCOs) that allow the frequency of the output signal to be varied by adjusting the amplitude of the input tuning voltage. Unlike traditional oscillators with a single fixed frequency, the company’s 16 new VCO models cover frequency bands ranging from 10 MHz to 4,350 MHz.

Fairview is targeting these VCOs at military electronics, SATCOM, test and measurement, and wireless communications. And applications include phase-locked loops, function generators, frequency synthesizers, receivers, electronic jamming equipment, and local oscillators.

The new VCOs offer tuning voltages ranging from 0.5 V to 20 V, output power from +4 dBm to +12 dBm, and supply voltage of 5 Vdc to 15 Vdc. And they incorporate 50-Ω internal matching to simplify integration onto the PCB. Moreover, second harmonics is as low as –25 dBc and phase-noise performance is as low as –120 dBc/Hz at 10-kHz offset.

These VCOs come in a 0.5-in. hermetically sealed surface-mount package to meet MIL-STD-883 and MIL-STD-202 environmental test conditions for shock, vibration, and temperature cycle. And all VCO models are RoHS- and REACH-compliant and are classified as EAR99.

Tim Galla, product manager at Fairview, claims that the rugged, SMT, and hermetically sealed packages allow these oscillators to perform in any environment, even in the most demanding conditions.
