General Description
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.
