Functional Diagram
General Description
The HMC329LC3B is a general purpose double
balanced mixer in a leadless RoHS compliant
SMT package that can be used as an upconverter
or downconverter between 24 and 32 GHz. This
mixer requires no external components or matching
circuitry. The HMC329LC3B provides excellent LO to
RF and LO to IF suppression due to optimized balun
structures. The mixer operates with LO drive levels
above +9 dBm. The HMC329LC3B eliminates the
need for wire bonding, allowing use of surface mount
manufacturing techniques.

LO
This pin is DC coupled and matched to 50 Ohm
from 24 to 32 GHz.
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.

This pin is DC coupled and matched to 50 Ohm
from 24 to 32 GHz.

N/C
No connection required. These pins may be connected to
RF/DC ground without affecting performance.
