Functional Diagram
General Description
The HMC557LC4 is a general purpose double
balanced mixer in a leadless RoHS compliant
SMT package that can be used as an upconverter
or downconverter between 2.5 and 7 GHz. This
mixer is fabricated in a GaAs MESFET process,
and requires no external components or matching
circuitry. The HMC557LC4 provides excellent LO to
RF and LO to IF isolation due to optimized balun
structures and operates with LO drive levels as low
as +9 dBm. The RoHS compliant HMC557LC4
eliminates the need for wire bonding, and is compatible
with high volume surface mount manufacturing
techniques.

IF
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 or sink more than 2 mA of current or part
non-function and possible part failure will result.

The circuit board used in this 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.
