MMIC VCOs (RFVC18xx Series)

The RFMD RFVC18xx series is a family of voltage controlled oscillators (VCO) with integrated RF output buffer amplifiers based on GaAs InGaP MMIC technology. The monolithic structure of the VCO ensures excellent temperature, shock, and vibration performance. With both broadband and narrowband options available these parts are suited for applications in the 4 to 12 GHz frequency range. Typical applications include military, satellite communications, test instrumentation, industrial and medical, aerospace, and CATV. All products in the family operate from a single positive supply voltage and deliver low phase noise performance with minimum power consumption. Each VCO comes in a compact, RoHS compliant 4.0 x 4.0mm QFN package.

  • Broadband and Narrowband Frequency Options
