WIDEBAND MMIC VCO w/ BUFFER

AMPLIFIER, 4 - 8 GHz

General Description

Features

Functional Diagram

The HMC586LC4B is a wideband GaAs InGaP

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 +18V. The

HMC586LC4B VCO operates from a single +5V sup-

ply, 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.
