General Description
The HMC587LC4B 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 oscilla-
tor’s monolithic construction. The Vtune port accepts
an analog tuning voltage from 0 to +18 volts. The
HMC587LC4B VCO operates from a single +5V
supply, 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 consump-
tion, and wide tuning range.
