chebyshev

Frequency Range from 1 kHz to 200 MHz

Band Rejection Filters are used to remove unwanted signals. Typical applications include filtering receivers that are so close to a transmitter that it swamps all other signals. In addition to these Chebyshev Band Rejection Filters, TTE also offers series B83, a notch filter for low frequency applications such as notching out 60 Hz, 120 Hz, etc. Chebyshev Band Rejection Filters are available for any center frequency from 1 kHz to 200 MHz.

  1.  Series, RC
  2. Number of poles, 6
  3. The “T” option specifies a filter with low THD for ADC/DAC testing.  When selected therein, THD is > -80dBc, -96dBc typical.
  4. “R” RoHS compliant.  Allow for longer lead time.
  5. The Notch Frequency, fn
  6. The -3dBc passband bandwidth.  It may also be specified as a percentage of fn.  Thus, instead of 22 MHz, use 22P.
  7. Terminations
  8. Case selection from the case selection guide.  “T” option cases are larger than standard.
