| HMC737LP4 / 737LP4E v00.1108 MMIC VCO w/ HALF FREQUENCY OUTPUT 14.9 - 15.5 GHz Features Dual Output: Fo = 14.9 - 15.5 GHz Fo/2 = 7.45 - 7.75 GHz Pout: +9 dBm Phase Noise: -105 dBc/Hz @ 100 kHz No External Resonator Needed 24 Lead 4x4mm SMT Package: 16mm2 Typical Applications The HMC737LP4(E) is ideal for: * Point to Point/Multipoint Radio * Test Equipment & Industrial Controls * SATCOM * Military End-Use Functional Diagram General Description The HMC737LP4(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC737LP4(E) integrate a resonator, negative resistance device, varactor diode and feature half frequency output. The VCO's phase noise performance is excellent over temperature, shock, and process due to the oscillator's monolithic structure. Power output is +9 dBm typical from a +4.2V supply voltage. The voltage controlled oscillator is packaged in a leadless QFN 4x4 mm surface mount package, and requires no external matching components. 12 VCOS WITH FO/2 OUTPUT - SMT Electrical Specifi cations, TA = +25 C, Vcc = +4.2V Parameter Frequency Range Power Output SSB Phase Noise @ 100 kHz Offset, Vtune= +5V @ RFOUT Tune Voltage Supply Current Tune Port Leakage Current (Vtune= 13V) Output Return Loss Harmonics/Subharmonics Pulling (into a 2.0:1 VSWR) Pushing @ Vtune= 5V Frequency Drift Rate 1/2 3/2 2.5 -45 -42 12 24 1.2 Vtune 1 120 150 Fo Fo/2 RFOUT RFOUT/2 6 -8 Min.
