HMC391LP4E

v03.0209 Typical Applications Low noise MMIC VCO w/Buffer Amplifier for: VSAT & Microwave Radio Radio Altimetry Test Equipment & Industrial Controls Military Functional Diagram 12 HMC391LP4 / 391LP4E MMIC VCO w/ BUFFER AMPLIFIER, 3.9 - 4.45 GHz Features Pout: +5.0 dBm Phase Noise: -106 dBc/Hz @100 KHz No External Resonator Needed Single Supply: +3V @ 30 mA 24 Lead 4x4mm QFN Package: 9 mm2 General Description The HMC391LP4 & HMC391LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. 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 structure. Power output is 5.0 dBm typical from a single supply of +3V @ 30 mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.
