General Description
The HMC508LP5 & HMC508LP5E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC508LP5 & HMC508LP5E integrate resonators, negative resistance devices, varactor diodes and feature a half frequency output. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is +15 dBm typical from a +5V supply. The
voltage controlled oscillator is packaged in a leadless QFN 5x5 mm surface mount package, and requires no external matching components.
