Butterworth

KB series

Frequency Range from 500 Hz to 1 GHz

Butterworth Bandpass Filters offer a monotonic passband and stopband response. Available packages include PCB, radial RF pins, SMT, SMA and BNC connectorized cases. These are available for low frequency, 10-20 kHz RFID applications, RF and microwave applications including ADC and DAC low distortion testing, data acquisition, receivers and transmitters. Specify any center frequency from 500 Hz to 1 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.

    The “T” option specifies a filter with low THD for ADC/DAC testing. When selected therein, THD is > -80dBc, -96dBc typical.
    “R” RoHS compliant. Allow for longer lead time.
    The Center Frequency, f_o
    The -3dBc passband bandwidth. It may also be specified as a percentage of f_o. Thus, instead of 535 kHz, use 5P.
    Terminations
    Case selection from the case selection guide. “T” option cases are larger than standard.
