Functional Diagram
General Description
The HMC567LC5 is a compact GaAs MCM I/Q
downconverter in a leadless RoHS compliant
SMT package. This device provides a small signal
conversion gain of 10 dB with a noise figure of 2.5 dB
and 35 dB of image rejection across the frequency
band. The HMC567LC5 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 HMC567LC5 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.
Typical Application
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.
