Krohn-Hite Corporation Continuous Time Fixed Frequency Filter Modules Module 3A

The Krohn-Hite 3A, 3B, 3C and 3D Series of continuous-time fixed-frequency precision active filter modules provide filtering in a 1 to 8-poles and 16-pole compact package, with the choice of cutoff frequencies, customer selectable from 1Hz to 2MHz low-pass and 1Hz to 600kHz high-pass. Choose between Butterworth and Bessel responses with input and output gain from 1 to 100 in 1% increments (0dB to 40dB). Functions of low-pass, high-pass and band-pass are available. Each module is factory tuned with customer-specified parameters of cutoff frequency, number of poles, response, function, single-ended or differential input configuration and input gains and output gains.
