HMC735LP5 / 735LP5E v03.0609 MMIC VCO w/ DIVIDE-BY-4 10.5 - 12.2 GHz Typical Applications Features The HMC735LP5(E) is ideal for: Dual Output: Fo = 10.5 - 12.2 GHz Fo/4 = 2.625 - 3.05 GHz • Point-to-Point/Multi-Point Radio • Test Equipment & Industrial Controls Pout: +17 dBm Phase Noise: -100 dBc/Hz @ 100 kHz Typ. • SATCOM • Military End-Use No External Resonator Needed 32 Lead 5x5mm SMT Package: 25mm2 Functional Diagram The HMC735LP5(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC735LP5(E) integrates resonators, negative resistance devices, varactor diodes and features a divide-by-4 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 +17 dBm typical from a +5V supply voltage. The prescaler function can be disabled to conserve current if not required. The voltage controlled oscillator is packaged in a leadless QFN 5x5 mm surface mount package, and requires no external matching components. 8 VCOS - SMT General Description Electrical Specifications, TA = +25° C, Vcc (Dig), Vcc (Amp), Vcc (RF) = +5V Parameter Frequency Range Power Output Min.
