Fairview Microwave Inc. (Allen, Tex.) now offers 16 new voltage-controlled oscillator (VCO) models covering bands from 10 MHz to 4350 MHz. Unlike traditional oscillators with a single fixed frequency, VCOs allow the frequency of the output signal to be varied by adjusting the amplitude of the input tuning voltage. These products are used in military electronics, SATCOM, test and measurement and wireless communications. Typical applications include phase locked loops, function generators, frequency synthesizers, receivers, electronic jamming equipment and local oscillators.
These VCOs deliver tuning voltages ranging from 0.5-20 V, output power from +4 dBm to +12 dBm and supply voltage of 5 Vdc to 15 Vdc. Designs incorporate 50 Ohm internal matching for simple integration onto a circuit board, 2nd harmonics as low as -25 dBc and phase noise performance as low as -120 dBc/Hz at 10 KHz offset. The oscillators come in a 0.5 inch hermetically sealed surface mount package designed to meet MIL-STD-883 and MIL-STD-202 environmental test conditions for shock, vibration and temperature cycle. All models are RoHS and REACH compliant and classified as EAR99.
