GENERAL DESCRIPTION
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.
