| HMC389LP4 / 389LP4E v03.0507 MMIC VCO w/ BUFFER AMPLIFIER, 3.35 - 3.55 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: +4.7 dBm Phase Noise: -112 dBc/Hz @100 KHz No External Resonator Needed Single Supply: 3V @ 41 mA QFN Leadless SMT Package, 16 mm2 Functional Diagram General Description The HMC389LP4 & HMC389LP4E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs with integrated resonators, negative resistance devices, varactor diodes, and buffer amplifiers. Covering 3.35 to 3.55 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 4.7 dBm typical from a single supply of 3V @ 41mA. The voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package. 10 VCOS & PLOs - SMT Electrical Specifications, TA = +25 C, Vcc = +3V Parameter Frequency Range Power Output SSB Phase Noise @ 100 kHz Offset, Vtune= +5V @ RF Output Tune Voltage (Vtune) Supply Current (Icc) (Vcc = +3.0V) Tune Port Leakage Current Output Return Loss Harmonics 2nd 3rd Pulling (into a 2.0:1 VSWR) Pushing @ Vtune= +5V Frequency Drift Rate 6 -7 -16 3.3 -3 0.4 0 41 10 1.5 Min.
