HMC391LP4 391LP4E / v03.0209 MMIC VCO w/ BUFFER AMPLIFIER, 3.9 - 4.45 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifi er for: Pout: +5.0 dBm • VSAT & Microwave Radio Phase Noise: -106 dBc/Hz @100 KHz • Radio Altimetry No External Resonator Needed • Test Equipment & Industrial Controls Single Supply: +3V @ 30 mA • Military 24 Lead 4x4mm QFN Package: 9 mm2 Functional Diagram General Description The HMC391LP4 & HMC391LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance 12 devices, varactor diodes, and buffer amplifi ers. Covering 3.9 to 4.45 GHz, the VCO’s phase noise performance is excellent over temperature, shock, vibration and process due to the oscillator’s monolithic T structure. Power output is 5.0 dBm typical from a M single supply of +3V @ 30 mA. The voltage controlled S oscillator is packaged in a low cost leadless QFN 4 x 4 - mm surface mount package.
