HMC738LP4E

HMC738LP4 / 738LP4E v02.0309 MMIC VCO w/ HALF FREQUENCY OUTPUT & DIVIDE-BY-16, 20.9 - 23.9 GHz Features Pout: +9 dBm Phase Noise: -95 dBc/Hz @ 100 kHz Typ. No External Resonator Needed 24 Lead 4x4mm SMT Package: 16mm² Typical Applications The HMC738LP4(E) is ideal for: • Point-to-Point Radios • Point-to-Multi-Point Radios / LMDS • VSAT Functional Diagram General Description The HMC738LP4(E) is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC VCO. The HMC738LP4(E) integrates a resonator, negative resistance device, varactor diode and divide-by-16 prescaler. 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 voltage controlled oscillator is packaged in a low cost leadless QFN 4x4 mm surface mount package 8 VCOS with Fo/2 OUTPUT - SMT Electrical Specifications, TA = +25° C, Vcc (RF), Vcc (DIG) = +5V Parameter Frequency Range Power Output Fo Fo/2 RF OUT RF OUT/2 RF OUT/16 3 -3.5 -7 -95 Vtune Icc (RF), Icc (DIG) 1 160 200 13 220 10 3 1/2 3/2 -23 -40 22 -90 3.5 Min.
