Avalanche noise in submicrometre pin diodes
Electronics Letters, 1997 It is shown that recent measurements of noise suppression in thin GaAs pin diodes by Hu et al. (1996) can be explained as a dead space phenomenon and are consistent with the /spl alpha///spl beta/ ratio approaching unity at high electric fields.

Channelized coplanar waveguide pin-diode switches [PDF]
Three different types of p-i-n diode, reflective CPW switches are presented. The first two switches are the series and the shunt mounted diode switches. Each has achieved greater than 15 dB of isolation over a broad bandwidth.
