Functional Diagram
General Description
The HMC554LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant SMT
package that can be used as an upconverter or
downconverter between 11 and 20 GHz. This mixer is
fabricated in a GaAs MESFET process, and requires
no external components or matching circuitry. The
HMC554LC3B provides excellent LO to RF and LO
to IF isolation due to optimized balun structures. The
RoHS compliant HMC554LC3B eliminates the need
for wire bonding, and is compatible with high volume
surface mount manufacturing techniques.

5
IF
This pin is DC coupled. For applications not requiring opera-
tion 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.
