A topology of switchable power splitter (SPWS) ink-jet printed on flexible Kapton substrate is developed in this paper. The SPWS circuit diagram integrating a Tee PWS is described based on the synoptic approach. The complete theoretical formulations of the SPWS reflection and transmission coefficients were established. The analytical expressions enabling to assess the Tee-PWS elementary output lines for the SPWS input matching are elaborated. To validate the relevance of the proposed SPWS, a proof of concept was synthesized, designed and implemented in microstrip hybrid technology by using the packaged switch biased with 3.3 V DC supply. The fabricated circuit was directly ink-jet printed on a low cost flexible Kapton® polyimide film, using a Dimatix DMP-2831 materials printer. Then, comparisons between the experimental and electromagnetic and circuit co-simulated S-parameters from the SPWS prototype were performed. The measured SPWS performance to operate in the IEEE standard 802.11a bands from 5.4-5.7 GHz was presented. The SPWS presents overall insertion losses of about-5.5 dB and-13 dB respectively for the switches on-and off-state. Furthermore, the input and output return losses are respectively with average value of about-11 dB in the expected operation frequency band.
