ADI HMC329A

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.
