HMC736LP4 / 736LP4E v01.0209 MMIC VCO w/ HALF FREQUENCY OUTPUT 14.5 - 15.0 GHz Typical Applications Features The HMC736LP4(E) is ideal for: Dual Output: Fo = 14.5 - 15.0 GHz Fo/2 = 7.25 - 7.5 GHz • Point to Point/Multipoint Radio • Test Equipment & Industrial Controls Pout: +9 dBm Phase Noise: -105 dBc/Hz @ 100 kHz • SATCOM • Military End-Use No External Resonator Needed 24 Lead 4x4mm SMT Package: 16mm2 Functional Diagram The HMC736LP4(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC736LP4(E) integrates 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.
