Low SSB Phase Noise: -95 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 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.

108646 Eval Board
[1] Reference this number when ordering complete evaluation PCB
The circuit board used in the 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 sufficient 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.
