General Description
The HMC904LC5 is a compact GaAs MMIC I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 12 dB with a noise figure of 3 dB
and 30 dB of image rejection across the frequency
band. The HMC904LC5 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 filter 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 HMC904LC5 is a
much smaller alternative to hybrid style image reject
mixer downconverter assemblies, and is compatible
with surface mount manufacturing techniques.
