Notech Filter Assembly
The WSA-00135 is a high performance dual notch filter assembly, providing low loss for B-band Cellular receive and transmit frequencies, while rejecting the primary A-band (824 MHz to 835 MHz) and extended A-band (845 MHz to 846.5 MHz) mobile uplink bands. It provides receive passbands of 835 MHz to 845 MHz and 846.5 MHz to 849 MHz and transmit passband of 869 MHz to 894 MHz. The WSA-00135 offers very low insertion loss of 1.25 dB maximum in the receive passbands and 0.4 dB maximum in the Tx passband while offering very high rejection of 35 dB minimum from 824 MHz to 833 MHz, and 23 dB minimum from 845.4 MHz to 846.1 MHz. The WSA-00135 provides passband return loss of 16 dB minimum in receive passbands and 18 dB minimum in the transmit passband. Power handling is specified at 200 watts CW and 4,000 watts peak instantaneous from 869 MHz to 894 MHz. Dimensions are 19 inches rack x 3U high x 15 inches deep. Connectors are N-F, and are rear rack chassis accessible. Operating temperature range is 0°C to +50°C. Intermodulation is rated at 110 dBm maximum within the receive passband with two carriers at +43 dBm each, separated at 880 MHz and 894 MHz.
