Abstract

This paper presents the simulation analysis on the potential application of matched bandstop to bandpass filter in filter integrated switch (FIS) design.The FIS consists of matched band-stop to bandpass filter integrated with singlepole-double-throw (SPDT) switch. The proposed design was demonstrated for 2.45 GHz applications in wireless data communication systems such as Bluetooth and Zigbee.The filter was based on L-shape lossy resonator,which can provide an absorptive feature. PIN diodes were used as switching elements for the SPDT switch and to reconfigure between band-stop and bandpass responses.Therefore,the key advantages of the proposed design are high isolation and good return loss at both ON-and OFF-state ports.As a result,the simulation showed the followings:higher than 10 dB of return loss and greater than 25 dB of isolation at the operation frequency.
