Functional Diagram
General Description
The HMC774LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant SMT
package that can be used as an upconverter or
downconverter between 7 and 34 GHz. This mixer
requires no external components or matching
circuitry. The HMC774LC3B provides excellent LO to
RF and LO to IF suppression due to optimized balun
structures. The mixer operates best with LO drive
levels above +15 dBm. The HMC774LC3B eliminates
the need for wire bonding, allowing use of surface
mount manufacturing techniques.

These pins are not connected internally; however, all data
shown herein was measured with these pins connected to
RF/DC ground externally.
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.
