Aeroflex Metelics Products

GaAs Detector/Mixer Diodes

The Aeroflex / Metelics low cost surface mount single and anti-parallel pairs of gallium arsenide Schottky diodes in QFN package 0503 (1.37 x 0.86 mm) can be used through millimeter wave frequencies as they have low capacitance and low resistance. They are passivated with silicon nitride and protected with polyimide for high reliability. Typical applications include detectors and single ended mixer on SMGS11 and single balanced and subharmonic pumped mixers and limiters on SMGS21 in instruments, microwave radios, VSAT, and police radar detectors.

  • Low capacitance and low resistance
  • Passivated with silicon dioxide
