General Description
The HMC505LP4 & HMC505LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 6.8 to 7.4 GHz, the VCO’s phase noise performance is excellent over temperature, shock and vibration due to the oscillator’s monolithic structure.
