HMC967LP4E
v04.1012
GaAs MMIC I/Q DOWNCONVERTER
21 - 24 GHz
General Description
FeaturesTypical Applications
The HMC967LP4E is a compact GaAs MMIC I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 15 dB with a noise gure of 2.5 dB
and 25 dBc of image rejection across the frequency
band. The HMC967LP4E utilizes an LNA followed by
an image reject mixer which is driven by an active x2
multiplier. The image reject mixer eliminates the need
for a lter following the LNA, and removes thermal
noise at the image frequency. I and Q mixer outputs
are provided and an external 90° hybrid is needed to
select the required sideband. The HMC967LP4E is a
much smaller alternative to hybrid style image reject
mixer downconverter assemblies, and is compatible
with surface mount manufacturing techniques.
