HMC512LP5 / 512LP5E v05.0811 Typical Applications Features Low noise MMIC VCO w/Half Frequency, Divide-by-4 Outputs for: Triple Output: Fo = 9.6 - 10.8 GHz Fo/2 = 4.8 - 5.4 GHz Fo/4 = 2.4 - 2.7 GHz • Point to Point/Multipoint Radio • Test Equipment & Industrial Controls • SATCOM • Military End-Use Functional Diagram VCOS with Fo/2 OUTPUT - SMT Pout: +9 dBm Phase Noise: -110 dBc/Hz @100 kHz Typ. No External Resonator Needed 32 Lead 5 x 5 mm SMT Package: 25 mm² General Description The HMC512LP5 & HMC512LP5E are GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCOs. The HMC512LP5 & HMC512LP5E 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 +9 dBm typical from a +5V supply voltage. The prescaler and RF/2 functions 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 Electrical Specifications, TA = +25° C, Vcc (Dig), Vcc (Amp), Vcc (RF) = +5V Parameter Frequency Range Power Output Min.
