Frequency Range from 500 Hz to 200 MHz
essel 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% fo |
| KT3 | 3 (6) | 3% to 10% fo |
| KT4 | 4 (8) | 3% to 10% fo |
| KT5 | 5 (10) | 3% to 10% fo |
| KT6 | 6 (12) | 3% to 10% fo |
Part Number Derivation:
| KT | 4 | *(R) | -144K | -4.32K | -50 | -3264 |
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
Notes:
- Operating Temperature Range:
0°C to +70°C - VSWR at fo: 1.5:1 Typical
- Input Power: 20 mW
- Series, KT
- Number of poles, 4
- “R” RoHS compliant. Allow for longer lead time.
- The Notch Frequency, fo
- The -3dBc passband bandwidth. It may also be specified as a percentage of fo. Thus, instead of 4.32 kHz, use 3P.
- Terminations
- Case selection from the case selection guide.
