The TMC Series from LARK Engineering are tunable bandpass filters that operate from 9 to 1000 MHz with a bandwidth of 2.2% to 10%. These bandpass filters have an insertion loss of less than 6 dB and can handle up to 30 dBm of power. The filters have 8 bits parallel tuning control and a tuning speed of under 50 microseconds. They are available in a module that measures 1.5 x 2.5 x 3.25 inches and are ideal for frequency hopping and secure communications systems.
