Sunnyvale, CA — Aeroflex/Metelics has released a family of surface mount GaAs and silicon Schottky mixer/detector diodes for high volume pick and place applications. These control devices are ...

Conveniently, a widely used terahertz mixer is the Schottky diode, which in its simplest form is just a metal/semiconductor interface. Figure 1: Design and image of the monolithically integrated ...

THz Schottky diode mixers are based on metal/GaAs interfaces; the GaAs layer must be highly doped (up to 10 18 cm −3) and the contact area must be less than 1 μm 2 in size 5.
