GaAs Millimeter Wave/Sub-Millimeter Wave Schottky Diodes.

GaAs Millimeter Wave/Sub-Millimeter Wave Schottky Diodes


Teledyne Scientific Company offers a wide variety of millimeter-wave and submillimeter-wave planar airbridged Schottky diodes for applications in the 10 GHz to over 2.5 THz range.

Unique Diode Properties

  • Junction capacitance as low as 2fF allowing cutoff frequency >2THz
  • Very low parasitic capacitance < 9fF
  • Ultra low series resistance < 3Ω
  • Airbridged anode contact for low parasitic operation
  • Fully passivated by SiN
  • Flip chip and beamlead geometry
  • Space qualifiable construction
  • MMIC backend process available for integrated passives and vias
  • Unique gold stand-off platforms for ruggedness in flip-chip applications
