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 VCOS with Fo/2 OUTPUT - SMT 8 8-1 Electrical Specifications, TA = +25 C, Vcc (RF), Vcc (DIG) = +5V Parameter Frequency Range Power Output Min.
