Elliptical Function – Anti-Aliasing

Frequency Range from 1 kHz to 200 MHz

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