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 semiconductor field effect transistor (MESFET) process, and requires no external components or matching circuitry.

FEATURES
   Conversion loss: 7.5 dB typical at 5.5 GHz to 10 GHz
   Local oscillator (LO) to radio frequency (RF) isolation: 45 dB
      typical at 5.5 GHz to 10 GHz
   LO to intermediate frequency (IF) isolation: 45 dB typical at
      10 GHz to 14 GHz
   Input third-order intercept (IIP3): 21 dBm typical at 10 GHz
      to 14 GHz
   Input P1dB: 11.5 dBm typical at 10 GHz to 14 GHz
   Input second-order intercept (IIP2): 55 dBm typical at 10 GHz
      to 14 GHz
   Passive double-balanced topology
   Wide IF bandwidth: dc to 6 GHz
   12-lead ceramic leadless chip carrier package

APPLICATIONS
   Point to point microwave radios
   Point to multipoint radios
   Military end use
   Instrumentation, automatic test equipment (ATE), and sensors
