Bandstop to Allpass Reconfigurable Filter Technique in SPDT Switch Design

Abstract: Abstract-In this paper, a bandstop to allpass reconfigurable filter technique is proposed in Single Pole Double Throw (SPDT) switch design. Proof of concept of the bandstop to allpass reconfigurable filter is presented. It is physically realized using transmission line and radial stub in 3.5 GHz band (3.4 to 3.6 GHz). The isolation, insertion loss and return loss of the SPDT switches are analyzed and to validate this technique the prototypes are fabricated using FR4 substrate with a thickness of 16 mm.

“…[31]. Besides, the design can be used in RF switch circuit as reported in [32]- [34]. Both designs in Figure 3 (a) and 3 (b) has different length of k-inverter between the resonators where design A has five times the quarter wavelength (5λ/4) and design B has three times the quarter wavelength (3λ/4).…”
