elliptical function

Frequency Range from 1 kHz to 200 MHz

Elliptical Function Highpass Filters exhibit both passband and stopband ripple. The passband ripple is ±0.25 dB typical. These are available for -3dB frequencies from 1 kHz to 200 MHz, covering AF, RF and microwave applications. Packages include PCB radial pins, SMA and BNC connectorized configurations.

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.
