Absorptive Bessel filters to 30 GHz

June 12, 2017 // By Jean-Pierre Joosting
Ideal for use in digital systems where truthful reproduction of waveforms is important, 4th order absorptive Bessel filters from RLC Electronics provide the excellent group delay response of Bessel filters while maintaining impedance matching far into the stop band.

Resistive elements are designed into these filters, resulting in a response that closely mimics the classic Bessel in both amplitude and phase. The filters are now available with -3 dB cut off frequencies as high as 30 GHz. A surface mount configuration is available to 4 GHz.
