Frequency Range from 500 Hz to 200 MHz

Gaussian Bandpass Filters are designed to pass a step function with zero overshoot and minimum rise time. Available packages include PCB, radial RF pins, SMA and BNC connectorized cases. These are available for RF and microwave applications including data acquisition, RFID, receivers and transmitters. Specify any center frequency from 500 Hz to 200 MHz.
