band rejection filters

TTE’s band rejection filters are available for any center frequency from 1 kHz to 200 MHz. For frequencies above or below that range please contact TTE for assistance.

Topologies & Features:
  • Butterworth Filters – offer monotonic passbands.
  • Chebyshev Filters – have a low ripple passband of ±0.25 dB typical.
  • Elliptical Function Filters – have a passband ripple of  ±0.25 dB typical. These filters are more selective than Butterworth or Chebyshev topologies

Technical information is provided for Chebyshev Filters; please contact TTE for assistance with Butterworth Filters and Elliptical Function Filters.


TTE offers its passive filters in the smallest practical sizes available; PCB, SMT or connectorized (BNC or SMA) cases are typically utilized, depending on the specific filter design.
