HMC588LC4B
WIDEBAND MMIC VCO w/ BUFFER
AMPLIFIER, 8.0 - 12.5 GHz
Features
Wide Tuning Bandwidth
Pout: +5 dBm
Low SSB Phase Noise: -93 dBc/Hz @100 kHz
No External Resonator Needed
Single Positive Supply: +5V @ 55 mA
RoHS Compliant 4 x 4 mm SMT Package
General Description
The HMC588LC4B is a wideband GaAs InGaP HBT
MMIC Voltage Controlled Oscillator which incor-
porates 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 +13V.
The HMC588LC4B 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 consumption, and
wide tuning range.
