Elliptic Notch Filter

The model 8NSP-1305-
/UX230-
O/O is a wideband elliptic notch filter for elimination of JTIDS frequency spectrum, from 1210 to 1400 MHz by 50 dB. With compact size, low loss and 100 W CW power handling, this unit supports all traffic communication between 933 and 1190 MHz and between 1420 and 1800 MHz. Through a combination of TEM, lumped elements and suspended-substrate technology, the RF performances per unit of volume are optimized.
