HMC737LP4 / 737LP4E v00.1108 MMIC VCO w/ HALF FREQUENCY OUTPUT 14.9 - 15.5 GHz Typical Applications Features The HMC737LP4(E) is ideal for: Dual Output: Fo = 14.9 - 15.5 GHz Fo/2 = 7.45 - 7.75 GHz • Point to Point/Multipoint Radio • Test Equipment & Industrial Controls Pout: +9 dBm Phase Noise: -105 dBc/Hz @ 100 kHz • SATCOM No External Resonator Needed • Military End-Use 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram 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.

Signal lines should have 50 ohm impedance while the package ground leads and backside ground paddle should be connected directly to the ground plane similar to that shown. A sufficient number of via holes should be used to connect the top and bottom ground planes. The evaluation circuit board shown is available from Hittite upon request.
