TTE has continually designed and manufactured Passive Band Rejection filters since it was established in 1956. These products are available for any notch frequency from 500Hz to 10GHz.
The Passive Band Rejection filters include Butterworth and Chebyshev topologies.
Butterworth Filters are more selective than Bessel Filters and offer both monotonic passband and stopbands.
Chebyshev Filters have a low ripple passband and monotonic stopbands. The passband ripple is 0.25dB typically.
Note that Passive Band Rejection filters have not been broken out into separate Miniature and micro-miniature categories. All of our filters are offered the smallest practical sizes available at TTE. All Passive Band Rejection filters are offered in PCB or SMT cases as well as Connectorized cases.
