Frequency Range from 1 kHz to 20 MHz

Elliptical Function Anti-Aliasing Bandpass Filters contain passband ripple and stop peaks and zeros. Available packages include PCB, radial RF pins, SMA and BNC connectorized cases. These are available for RF and microwave applications including ADC and DAC low distortion testing, data acquisition, receivers and transmitters. Specify any center frequency from 1 kHz to 20 MHz.

  2. The “T” option specifies a filter with low THD for ADC/DAC testing. When selected therein, THD is > -80dBc, -96dBc typical.
  3. “R” RoHS compliant. Allow for longer lead time.
