GENERAL DESCRIPTION
The HMC329A chip is a general-purpose, double balanced
mixer that can be used as an upconverter or downconverter
from 22 GHz to 38 GHz in a small chip area of 0.87 mm ×
0.58 mm. This mixer requires no external component or
matching circuitry. The HMC329A provides excellent local
oscillation (LO) to radio frequency (RF) and LO to intermediate
frequency (IF) suppression due to optimized balun structures.
The mixer operates with LO drive levels at 13 dBm or above.
