Functional Diagram
General Description
The HMC569LC5 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 2.5
dB and 32 dB of image rejection. The HMC569LC5
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 HMC569LC5 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.
