Bessel

KT Series

Frequency Range from 500 Hz to 200 MHz

Bessel Bandpass Filters exhibit a constant time delay through the filters passband. Available packages include PCB, radial RF pins, SMT, SMA and BNC connectorized cases. These are available for RF and microwave applications including data acquisition, receivers and transmitters. Specify any center frequency from 500 Hz to 200 MHz.
