GaAs Schottky Diode Products

Teratech Components manufactures a wide range of GaAs millimetre wave and sub-millimetre wave air-bridged Schottky diodes for applications from 75 GHz to 1 THz.  Although we have a range of standard products, we are keen to work with our customers in order to ensure the very best product for each application; we can modify our diode structures to suit your requirements and can fabricate diodes to customer designs.  We also have a wide range of diodes under development; please contact us for further information.

Key Diode Features

  • Junction capacitance as low as 1 fF allowing a cut-off frequency > 2 THz
  • Air-bridged anode contact for low parasitic capacitance
  • Ultra low series resistance
  • Flip-chip designs
  • Beam-lead designs
  • Choice of substrates: GaAs, AlN and Quartz

  • AP2 Series: High frequency anti-parallel mixer diodes

Designed for sub-harmonic mixer and high order harmonic mixers from 400 to 800 GHz

The AP2 series of diodes combines the ultra-low parasitic capacitance and series resistance of the AP1 series in a geometry optimised for applications in the range 400 to 800 GHz. These diodes are available with a range of junction capacitance values from 1 to 5 fF.

  • AS3 Series: Anti-series varactors  ~ 150 to 200 GHz

Designed for frequency doublers from 150 to 220 GHz

The AS3 series of varactor diodes are designed for applications in frequency doublers multiplying frequencies in the range 150 to 220 GHz. A transfer substrate process is available which replaces the underlying GaAs substrate with aluminium-nitride in order to improve power handling. These diodes are available with a range of junction capacitance values from 30 to 50 fF.

  • AS4 Series: Anti-series varactors  ~ 75 – 110 GHz

Designed for frequency doublers from 75 – 110 GHz

The AS4 series of varactor diodes are designed for applications in frequency doublers multiplying frequencies in the range 75 to 110 GHz.  As with the AS3 Series diodes, a transfer substrate process is available which replaces the underlying GaAs substrate with aluminium-nitride in order to improve power handling.  Junction capacitance values from 30 to 50  fF are available.
