A switchable bandpass filter that can operate between 60 GHz and E-band spectrum, capable of providing good channel isolation is presented. A RF MEMS SPDT is designed for the switching element between the two bands. Back-to-back cantilever switches are used for maximum isolation. New circuit models for the inductively coupled inverters and short circuit stubs are proposed. Measurement results show good correlation to our simulations. Better than 15 dB return loss and 5 dB insertion loss in both 60 GHz and Eband are measured. With the introduction of transmission zero, rejection between the two operational bands is better than 20 dB.
