| v00.0804 HMC506LP4 MMIC VCO w/ BUFFER AMPLIFIER, 7.8 - 8.7 GHz Features Pout: +14 dBm Phase Noise: -103 dBc/Hz @100 KHz No External Resonator Needed Single Supply: +3V @ 77 mA QFN Leadless SMT Package, 16 mm2 Typical Applications Low noise MMIC VCO w/Buffer Amplifier for: * VSAT Radio * Point to Point/Multipoint Radio * Test Equipment & Industrial Controls * Military End-Use Functional Diagram General Description The HMC506LP4 is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO with integrated resonator, negative resistance device, varactor diode, and buffer amplifier. Covering 7.8 to 8.7 GHz, the VCO's phase noise performance is excellent over temperature, shock and vibration due to the oscillator's monolithic structure. Power output is +14 dBm typical from a single supply of +3.0V @ 77 mA. The voltage controlled oscillator is packaged in a leadless QFN 4 x 4 mm surface mount package. 15 VCOs - 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 7 1 77 10 11.0 Min.
