| HMC588LC4B v01.1205 WIDEBAND MMIC VCO w/ BUFFER AMPLIFIER, 8.0 - 12.5 GHz Typical Applications Low Noise wideband MMIC VCO is ideal for: * Industrial/Medical Equipment * Test & Measurement Equipment * Military Radar, EW & ECM Features Wide Tuning Bandwidth Pout: +5 dBm Low SSB Phase Noise: -93 dBc/Hz @100 kHz No External Resonator Needed Single Positive Supply: +5V @ 55 mA RoHS Compliant 4 x 4 mm SMT Package 9 VCOs & PLOs - SMT Functional Diagram General Description The HMC588LC4B is a wideband GaAs InGaP HBT 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 +13V. The HMC588LC4B VCO operates from a single +5V supply, consumes only 55 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. Electrical Specifications, TA = +25 C, Vcc = +5V Parameter Frequency Range Power Output SSB Phase Noise @ 100 kHz Offset SSB Phase Noise @ 10 kHz Offset Tune Voltage (Vtune) Supply Current (Icc) (Vcc = +5.0V) Tune Port Leakage Current (Vtune = +13V) Output Return Loss 2nd Harmonic Pulling (into a 2.0:1 VSWR) Pushing @ Vtune= +5V Frequency Drift Rate 7 -18 4 100 0.3 0 40 2 Min.
