General Description

Features

Functional Diagram

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.
