HMC466LP4 / 466LP4E v03.1109 MMIC VCO w/ BUFFER AMPLIFIER, 6.1 - 6.72 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for: Pout: +4.5 dBm • VSAT & Microwave Radio Phase Noise: -101 dBc/Hz @100 KHz • CATV & Broadcast Relays No External Resonator Needed • Test Equipment & Industrial Controls Single Supply: +3V @ 31 mA • Military 24 Lead 4x4mm QFN Package: 16 mm2 Functional Diagram General Description The HMC466LP4 & HMC466LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 6.1 to 6.72 GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic structure. Power output is 4.5 dBm typical from a single supply of 3V @31mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.
