Anatech Electronics lumped-element (LC) bandstop filters are available from 500 kHz to 5 GHz with 2 to 8 sections, notch bandwidth from 1% to 20%, and passband-to-notch ratios from 2:1 to 20:1. They have a high Q factor that results in lower insertion loss and greater selectivity. Standard designs have a 0.05-dB Chebyshev response and other response types such as Butterworth, elliptic, and Bessel are available as well as special shapes. Anatech LC bandstop filters range in size from 1 to more than 10 in. long and the width and height vary depending on the application. Power handling capability up to 500 W can be specified.
All packages can be manufactured in surface mount, connectorized, printed circuit board mount, drop-in, or other configurations suitable for the frequency range of the filter. Parameters such as insertion loss and RF power handling ability can be enhanced by using special design techniques. Anatech Electronics can manufacture custom filters and special packaging to meet customer requirements.
