Abstract
Electronically reconfigurable filters have attracted more attention of researchers as they replace bulky filter banks in the wireless systems. Reconfigurability can be achieved either in terms of bandwidth or in terms of centre frequency. In either way a tuning element such as RF MEMS, Varactor diode, p-i-n diode or tunable capacitor can be used to tune the bandwidth or centre frequency. Since these elements can be easily integrated on microstrip printed boards, exploring new design techniques of tunable filters is an active area of research. This paper presents design of electronically tunable dual band Bandpass filter. Reconfigurability is achieved by adding two parallel resonators which are tuned to two different bands. Dual band is achieved by adding two parallel resonators. The filter designed is third order bandpass filter; hence there are three parallel identical resonator sections. The designed filter achieves reconfigurability in terms of both bandwidth and centre frequency.
