General Description
The HMC509LP5 & HMC509LP5E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC
VCOs. The HMC509LP5 & HMC509LP5E integrate
resonators, negative resistance devices, varactor
diodes and feature a half frequency output. The VCO’s
phase noise pe rformance is excelle nt over temperature,
shock, and process due to the oscillator’s monolithic
structure. Power output is +13 dBm typical from a +5V
supply. The voltage controlled oscillator is packaged
in a leadless QFN 5x5 mm surface mount package,
and requires no external matching components.

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 backside 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.
