Bessel

KT Series

Frequency Range from 500 Hz to 200 MHz

Bessel Bandpass Filters exhibit a constant time delay through the filters passband. Available packages include PCB, radial RF pins, SMT, SMA and BNC connectorized cases. These are available for RF and microwave applications including data acquisition, receivers and transmitters. Specify any center frequency from 500 Hz to 200 MHz.

Series Number	Number of Pole Pairs (Elements)	Bandwidth Selection -3dBc
KT2	2 (4)	3% to 10% f_o
KT3	3 (6)	3% to 10% f_o
KT4	4 (8)	3% to 10% f_o
KT5	5 (10)	3% to 10% f_o
KT6	6 (12)	3% to 10% f_o

Notes:

Operating Temperature Range:
0°C to +70°C
VSWR at f_o: 1.5:1 Typical
Input Power: 20 mW

1. 1. 1. Series, KT
    2. Number of poles, 4
    3. “R” RoHS compliant. Allow for longer lead time.
    4. The Notch Frequency, f_o
    5. The -3dBc passband bandwidth. It may also be specified as a percentage of f_o. Thus, instead of 4.32 kHz, use 3P.
    6. Terminations
    7. Case selection from the case selection guide.
