HMC733LC4B

HMC733LC4B v02.0810 WIDEBAND MMIC VCO w/ BUFFER AMPLIFIER, 10 - 20 GHz Features Wide Tuning Bandwidth Pout: +3 dBm Low SSB Phase Noise: -90 dBc/Hz @100 kHz No External Resonator Needed Single Positive Supply: +5V @ 70 mA RoHS Compliant 4 x 4 mm SMT Package Typical Applications Low Noise wideband MMIC VCO is ideal for: • Industrial/Medical Equipment • Test & Measurement Equipment • Military Radar, EW & ECM Functional Diagram General Description The HMC733LC4B is a wideband MMIC Voltage Controlled Oscillator which incorporates the resonator, negative resistance device, and varactor diode. Output power and phase noise performance are excellent over temperature due to the oscillator’s monolithic construction. The Vtune port accepts an analog tuning voltage from 0 to +22V. The HMC733LC4B VCO operates from a single +5V supply, consumes only 70 mA of current, and is housed in a RoHS compliant SMT package. This wideband VCO uniquely combines the attributes of ultra small size, low phase noise, low power consumption, and wide tuning range. 8 WIDEBAND VCOS - SMT Electrical Specifications, TA = +25° C, Vcc = +5V Parameter Frequency Range Power Output SSB Phase Noise @ 10 kHz Offset SSB Phase Noise @ 100 kHz Offset Tune Voltage (Vtune) Supply Current (Icc) (Vcc = +5V) Tune Port Leakage Current (Vtune = +23V) Output Return Loss 2nd Harmonic Pulling (into a 2.0:1 VSWR) Vcc Pushing, Vtune = +20V, F = 20 GHz Frequency Drift Rate @ 10 GHz Frequency Drift Rate @ 20 GHz -0.25 70 25 10 -20 15 -90 -0.25 - 0.80 Min.
