TTE Designs
Frequency Range from 100 Hz to 200 MHz
TTE Designed Lowpass Filters are similar to Elliptical Function Filters. They exhibit both passband and stopband ripple. The passband ripple is ±0.25 dB typical. These filters are available for -3dB frequencies from 100 Hz to 200 MHz. They are available with a low THD option and are suitable for some ADC and DAC applications.
| Series No. | No. of Poles | f-3dBc Range |
|---|---|---|
| J73 | 7 | from 100 Hz to 200 MHz |
| J83 | 9 | from 100 Hz to 200 MHz |
| J93 | 11 | from 100 Hz to 200 MHz |
| J77 | 7 | from 100 Hz to 200 MHz |
| J87 | 9 | from 100 Hz to 200 MHz |
| J97 | 11 | from 100 Hz to 200 MHz |
Part Number Derivation:
| J87 | *(T) | **(R) | -5M | -50 | -65B |
| 1/2 | 3 | 4 | 5 | 6 | 7 |
1) Series, J87
2) Number of poles, 9
*3) The “T” option specifies a filter with low THD for ADC/DAC testing. When selected the minimum THD is > -80dBc, -96dBc typical.
**4) “R” RoHS compliant. Allow for longer lead time.
5) f-3dBc
6) Terminations
7) Case selection from the case selection guide. “T” option cases are larger than standard.
Notes:
Operating Temperature Range:
0°C to +70°C
VSWR: 1.5:1 Typical
Input Power: 20 mW
