Functional Diagram
General Description
The HMC869LC5 is a 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 2.8 dB and 32 dB of image
rejection. The HMC869LC5 utilizes an LNA followed
by an image reject mixer which is driven by an LO buf-
fer amplifier. The image reject mixer eliminates the
need for a filter following the LNA, and removes ther-
mal noise at the image frequency. I and Q mixer out-
puts are provided and an external 90° hybrid is needed
to select the required sideband. The HMC869LC5 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.
