on microstrip line is presented at 2GHz. A silicon switch is
exposed to incident signal power of up to 1W and controlled via
illumination with a range of optical intensities at a wavelength of
980nm in order to characterise the linearity in terms of harmonic
content. Reported single tone output third order intercept (TOI)
was measured as 63dBm under 200mW of optical incident light.
The study presents photoconductive switches as a promising
alternative to conventional microwave switches in high power
applications.
