5.5 GHz to 14 GHz, GaAs MMIC Fundamental Mixer

The HMC558A is a general-purpose, double-balanced mixer in a leadless RoHS compliant SMT package that can be used as an upconverter or downconverter between 5.5 GHz and 14 GHz. This mixer is fabricated in a gallium arsenide (GaAs) metal semi-conductor field effect transistor (MESFET) process, and requires no external components or matching circuitry.

The HMC558A provides excellent LO to RF and LO to IF isolation due to optimized balun structures, and operates with LO drive levels as low as 9 dBm. The RoHS compliant HMC558A eliminates the need for wire bonding, and is compatible with high volume surface-mount manufacturing techniques.
