The design of the four-channel switched filter bank in the S- and C-band using p-i-n-diode switches is described in a paper published in the October issue of IEEE-MTT Transactions. The paper by F. Gentili, L. Urbani, G. Bianchi, L. Pelliccia, R. Sorrentino is entitled “p-i-n-Diode-Based Four-Channel Switched Filter Bank With Low-Power TTL-Compatible Driver”. Narrowband filters designed on suspended substrate stripline lead to an average Q factor of 580. Spurious responses are suppressed from DC to roughly 19 GHz. The biasing circuit is TTL compatible. The abstract of the paper is available here.
