Functional Diagram
General Description
The HMC512LP5 & HMC512LP5E are GaAs InGaP
Heterojunction Bipolar Transistor (HBT) MMIC VCOs.
The HMC512LP5 & HMC512LP5E integrate resona-
tors, negative resistance devices, varactor diodes
and feature half frequency and divide-by-4 outputs.
The VCO’s phase noise performance is excellent over
temperature, shock, and process due to the oscilla-
tor’s monolithic structure. Power output is +9 dBm
typical from a +5V supply voltage. The prescaler and
RF/2 functions can be disabled to conserve current if
not required. The voltage controlled oscillator is pack-
aged in a leadless QFN 5x5 mm surface mount pack-
age, and requires no external matching components.
