HMC386LP4 v01.0604 MICROWAVE CORPORATION MMIC VCO w/ BUFFER AMPLIFIER, 2.6 - 2.8 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifier for: Pout: +5 dBm • Wireless Infrastructure Phase Noise: -114 dBc/Hz @100 kHz • Industrial Controls No External Resonator Needed • Test Equipment Single Supply: 3V @ 35 mA • Military QFN Leadless SMT Package, 16 mm2 Functional Diagram General Description The HMC386LP4 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO with integrated resonator, negative resistance device, varactor diode, and buffer amplifier. Covering 2.6 to 2.8 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 dBm typical from a single supply of 3V @ 35mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4 x 4 mm surface mount package.
