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.
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.
