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.
