The HMC8362 is a gallium arsenide (GaAs), quadband, monolithic microwave integrated circuit (MMIC), voltage controlled oscillator (VCO) designed to offer wideband capabilities without compromising on phase noise performance. The device integrates four independent, narrow-band VCOs with overlapping frequency bands, operating at a fundamental frequency range of 11.90 GHz to 18.30 GHz. The consistent tuning sensitivity across all frequency bands simplifies the synthesizer loop filter design.The tuning port is common to all VCO cores for a simpler design of the phase-locked loop (PLL) feedback path. The HMC8362 also offers a low typical current consumption of 72 mA for power sensitive applications.The HMC8362 integrates resonators, negative resistance devices, and varactor diodes. The monolithic structure of the oscillator offers very low phase noise, optimal temperature stability, and is immune to vibration and process variation.The four VCOs are packaged in a single, 6 mm × 6 mm, surface-mount lead frame chip scale package (LFCSP), and require no external matching components.Combined with a high frequency, high performance phase-locked loop (PLL), the ADF41513, the HMC8362 offers a complete RF or microwave frequency generation solution.APPLICATIONSElectronic test and measurementIndustrial and medical instrumentationPoint to point and multipoint radiosAerospace and defenseWireless communication infrastructure
