The device integrates four independent, narrow-band VCOs with overlapping frequency bands, operating at a fundamental frequency range of 18.10 GHz to 26.60 GHz. The consistent tuning sensitivity across all frequency bands simplifies the synthesizer loop filter design. The tuning port is mon to all VCO cores for a simpler design of the phase-locked loop (PLL) feedback path. The HMC8364 also offers a low typical current consumption of 99 m A for power sensitive applications. The HMC8364 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...
