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 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 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.

Interface Schematic
This pin is DC coupled for applications not requiring
operation to DC. This port should be DC blocked
externally using a series capacitor whose value has
been chosen to pass the necessary frequency range.
For operation to DC, this pin must not sink / source more
than 3 mA of current or part non-function and possible
failure will result.
This pin is AC coupled
and matched to 50 Ohms.

Note: LSB and USB is determined by GND on Hybrid

111225 Evaluation Board
The circuit board used in the final application
should use RF circuit design techniques. Signal
lines should have 50 Ohm impedance while the
package ground leads and exposed paddle should
be connected directly to the ground plane similar
to that shown. A sufficient number of via holes
should be used to connect the top and bottom
ground planes. The evaluation circuit board shown
is available from Hittite upon request.
