Abstract

This paper presents a third order ultra-wideband filter (3.1 GHz - 10.6 GHz) with a reconfigurable WLAN notch at 5.8 GHz. Filter reconfiguration in practice may be achieved by a switching element such as RF MEMs, a PIN diode or an optical switch. The switching element was modeled in simulation as a variable conductance line. The filter response shows a sharp rejection of the WLAN band and very low pass-band insertion loss. The quasi-elliptic nature of the bandpass response also contributes towards excellent lower and upper skirt selectivity.
