The WSA-00100 is a dual duplexer assembly, consisting of separate EGSM (880 to 915 MHz Rx and 925 to 960 MHz Tx) and DCS (1710 to 1785 MHz Rx and 1805 to 1880 MHz Tx) duplexers in a common assembly. The WSA-00100 is ideally suited for dual band mobile phone testing or equally, in Pico and Micro-Cellular base stations or in-building systems where GSM and DCS services are shared on a common transmission line or antenna.

The WSA-00100 is configured with common antenna, receive and transmit ports, conveniently facilitating Tx/Rx functionality testing. The WSA-00100 offers minimum 50 dB isolation from all Tx to Rx and Rx to Tx passbands, while maintaining 1.2 dB maximum EGSM and 1.0 dB maximum DCS passband insertion loss. Passband ripple is specified at 0.8 dB p-p maximum and return loss at 14 dB minimum. Antenna to receive rejection is specified at 50 dB minimum from DC to 845 MHz, 925 to 1630 MHz and 1805 to 2550 MHz. Transmit to Antenna port rejection is specified at 50 dB minimum DC to 915 MHz, 995 to 1785 MHz and 1960 to 2550 MHz. Maximum transmit path power handling is specified as 100 watts CW and 1000 watts peak instantaneous over an operating temperature range of 0 ° C to +50 ° C. Dimensions are 13.19 inches L × 5.94 inches W × 3.0 inches H (nominally 335 mm × 150.9 mm × 76.2 mm), excluding N-F connectors.
