HMC588LC4B v01.1205 WIDEBAND MMIC VCO w/ BUFFER AMPLIFIER, 8.0 - 12.5 GHz Typical Applications Features Low Noise wideband MMIC VCO is ideal for: Wide Tuning Bandwidth • Industrial/Medical Equipment Pout: +5 dBm • Test & Measurement Equipment Low SSB Phase Noise: -93 dBc/Hz @100 kHz • Military Radar, EW & ECM No External Resonator Needed Single Positive Supply: +5V @ 55 mA RoHS Compliant 4 x 4 mm SMT Package 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.
