This paper presents the evaluation of nonlinear distortion in reconfigurable Ultra-wideband (UWB) filter. An optical switch is used to switch the filter from bandpass to band stop response at the same UWB spectrum. The switch, which comprises of a silicon dice activated using near infrared light is investigated and the filter is evaluated for potential nonlinearity due to the presence of the switch. The filter was tested for nonlinear distortions when the Optical Switch was ON using 5MHz QPSK signal. © 2013 IEEE.
