APPLICATIONS
Point to point microwave radios Point to multipoint radios Military end use Instrumentation, automatic test equipment (ATE), and sensors FUNCTIONAL BLOCK DIAGRAM RF HMC558A LO IF 15000-001 Figure 1. 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.
