HMC388LP4 / 388LP4E v02.0805 MMIC VCO w/ BUFFER AMPLIFIER, 3.15 - 3.4 GHz Typical Applications Low noise MMIC VCO w/Buffer Amplifier for: • Wireless Local Loop (WLL) • VSAT & Microwave Radio • Test Equipment & Industrial Controls • Military Features Pout: +4.9 dBm Phase Noise: -113 dBc/Hz @100 KHz No External Resonator Needed Single Supply: 3V @ 39 mA QFN Leadless SMT Package, 16 mm2 9 VCOs & PLOs - SMT Functional Diagram General Description The HMC388LP4 & HMC388LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 3.15 to 3.4 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 4.9 dBm typical from a single supply of 3V @ 39mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package.
