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 oscillator’s 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.
