General Description
The HMC568LC5 is a compact GaAs MCM I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 14 dB with a noise figure of 2 dB and
33 dB of image rejection. The HMC568LC5 utilizes an
LNA followed by an image reject mixer which is driven
by an LO buffer amplifier. 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
HMC568LC5 is a much smaller alternative to hybrid
style image reject mixer downconverter assemblies,
and it eliminates the need for wire bonding by allowing
the use of surface mount manufacturing techniques.
