Functional Diagram
General Description
The HMC523LC4 is a compact general purpose I /Q
MMIC mixer in a leadless RoHS compliant SMT package, which can be used as either an Image Reject
Mixer or a Single Sideband Upconverter. The mixer
utilizes two standard Hittite double balanced mixer
cells and a 90 degree hybrid fabricated in a GaAs
MESFET process. A low frequency quadrature hybrid
was used to produce a 100 MHz USB IF output. This
product is a much smaller alternative to hybrid style
Image Reject Mixers and Single Sideband Upconverter assemblies. The HMC523LC4 eliminates the
need for wire bonding allowing 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 IF
frequency range. For operation to DC, this pin must not
source/sink more than 3mA of current or part non-function
and possible part failure will result.
This pin is AC coupled and matched to
50 Ohms from 15 to 23 GHz.

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.
