HMC531LP5 / 531LP5E v00.1105 Typical Applications Features Low noise MMIC VCO w/Half Frequency, Divide-by-4 Outputs for: Dual Output: Fo = 13.6 - 14.9 GHz Fo/2 = 6.8 - 7.45 GHz • VSAT Radio Pout: +7 dBm • Point to Point/Multipoint Radio Phase Noise: -110 dBc/Hz @100 kHz Typ. • Test Equipment & Industrial Controls No External Resonator Needed • Military End-Use QFN Leadless SMT Package, 25 mm2 Functional Diagram General Description The HMC531LP5 & HMC531LP5E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC531LP5 & HMC531LP5E integrate resonators, negative resistance devices, varactor diodes and feature half frequency and divide-by-4 outputs. The VCO’s phase noise performance is excellent over temperature, shock, and process due to the oscillator’s monolithic structure. Power output is +7 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.
