HMC6475LC4B v06.0519 WIDEBAND MMIC VCO WITH BUFFER AMPLIFIER 3.90 - 7.50 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: -106 dBc/Hz 100 kHz Satcom No External Resonator Needed Military Radar, EW, & ECM Single Positive Supply: +5V 53 mA Ceramic Leadless SMT Package: 16 mm Functional Diagram General Description The HMC6475LC4B 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 oscillators monolithic construction. The Vtune port accepts an analog tuning voltage from 0 to +23V. The HMC6475LC4B VCO operates from a single +5V supply, consumes only 53 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.
