HMC532LP4 532LP4E / v01.0508 MMIC VCO w/ BUFFER AMPLIFIER, 7.1 - 7.9 GHz Typical Applications Features Low noise MMIC VCO w/Buffer Amplifi er for: Pout: +14 dBm • VSAT Radio Phase Noise: -103 dBc/Hz @100 KHz • Point to Point/Multipoint Radio No External Resonator Needed • Test Equipment & Industrial Controls Single Supply: +3V @ 85 mA • Military End-Use 24 Lead 4x4mm QFN Package: 9 mm2 Functional Diagram General Description The HMC532LP4 & HMC532LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance 12 devices, varactor diodes, and buffer amplifi ers. Covering 7.1 to 7.9 GHz, the VCO’s phase noise performance is excellent over temperature, shock and vibration due to the oscillator’s monolithic struc- T ture. Power output is +14 dBm typical from a single M supply of +3V @ 85 mA. The voltage controlled S oscillator is packaged in a leadless QFN 4 x 4 mm - surface mount package.
