Abstract

This paper proposes a reconfigurable frequency and function between the feeding network and Single Pole Double Throw (SPDT) switch in a single design. In order to realize a reconfigurable function and frequency for the feeding network and SPDT switch, a Positive Intrinsic Negative (PIN) diode is used. The feeding network consists of two modified Wilkinson power dividers (WPDs), which operates at 2.5 GHz and 3.5 GHz. For the SPDT switch function, PIN diodes are added in the input and output ports of the feeding network to turn on or off the output port. Then, shorted stub is placed into the output port for matching when the feeding network function is changed to a SPDT switch. The proposed design realized a reconfigurable function that can either operate as a feeding network or SPDT switch by using PIN diodes and can be used for antenna array or power amplifiers applications. The proposed design shows good S-parameters performance at 2.5 GHz and 3.5 GHz based on simulation results acquired from a software of the Advanced Design System (ADS). The measurement results, however, indicate a frequency shift. Although the results of measurements were correlated to simulations, the resonant frequency was shifted due to the parasitic reactance of the PIN diode.
