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.

Series Number Number of Pole Pairs (Elements) Bandwidth Selection -3dBc
RC3 3 (6) 20% to 100% fn
RC4 4 (8) 20% to 100% fn
RC5 5 (10) 20% to 100% fn
RC6 6 (12) 20% to 100% fn

Part Number Derivation:

RC 6 *(T) **(R) -100M -22M -50 -69A
1 2 3 4 5 6 7 8

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.

Notes:

Operating Temperature Range:
0°C to +70°C

Passband VSWR: 1.5:1 Typical

Input Power: 20 mW
