Switched Filter Banks
Switched Filter Banks typically include multiple filter topologies, including PIN diode and MMIC switch sub-circuits to achieve operational bandwidths of greater than 3 octaves. Pin Diode Based Switched Filter Banks provide the highest level of signal isolation, higher operating power levels, and lower insertion loss and achieve switching speeds of < 40 nanoseconds. GaAs MMIC Based Switched Filter Banks provide switching times as low as 10 nanoseconds with very low power consumption and have the inherent advantage of supporting multi-octave frequency bands with extremely low power consumption.
