        <p>This article presents the results of the design of a four-channel switched filter bank for the centimeter band manufactured as a monolithic microwave integrated circuit based on domestic GaAs pHEMT technology. The switched filter bank includes a set of bandpass filters operating in four sub-bands of most of the C-, X- and Ku-bands, as well as broadband SP4T switches. The bandpass filters of the lower sub-bands are designed using lumped elements, and higher sub-bands filters are designed using microstrip hairpin resonators. The SP4T switch is based on SPST switches, each of which contains one series- and three parallel-connected field-effect transistors. The switched filter bank has following parameters: insertion losses of no more than 10.8 dB, stopband suppression of at least 43 dB at 30% offset or more from the passband center frequency, and a voltage standing wave ratio of no more than 1.8 in the passband.</p>
