General Description
Features
Functional Diagram
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 performance is excellent over tem-
perature, 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.
Dual Output: Fo = 7.8 - 8.8 GHz
Fo/2 = 3.9 - 4.4 GHz
Pout: +13 dBm
Phase Noise: -115 dBc/Hz @100 kHz Typ.
No External Resonator Needed
32 Lead 5x5mm SMT Package: 25mm²

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 backside ground paddle should be con-
nected 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.
