Single Positive Supply: +5V @ 55 mA

RoHS Compliant 4 x 4 mm SMT Package

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 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.

The circuit board used in the  nal application
should use RF circuit design techniques. Signal
lines should have 50 ohm impedance while the
package ground leads and exposed ground paddle
should be connected directly to the ground plane
similar to that shown. A suf cient number of via
holes should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
