Frequency Range from 500 Hz to 10 GHz

Chebyshev Bandpass Filters contain slight passband ripple while offering a monotonic stopband response. Available packages include PCB, radial RF pins, SMT, SMA and BNC connectorized cases. These are available for RF and microwave applications including transmitters, receivers, low frequency, 10-20 kHz, RFID, ADC and DAC low distortion testing, data acquisition, receivers and transmitters. Specify any center frequency from 500 Hz to 10 GHz.

TTE offers a low THD (low distortion) filter option for this series. Please refer to the Part Number Derivation section below where the “T” option is mentioned.

  2. Number of poles, &
  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 Center Frequency, fo
  6. The -3dBc passband bandwidth. It may also be specified as a percentage of fo. Thus, instead of 12.5 MHz, use 10P.
