The 7702BPX-IF-B50 2x1 RF protection switches for IF frequencies provide automatic changeover functionality to provide bypass protection for RF signals from 10MHz to 850MHz. Typical applications include main/standby failover protection for 70/140MHz uplink applications. When used for automatic changeover, the 7702BPX-IF have a MAIN input and a STANDBY input. It will automatically switch to the Standby input when the Main input power is weak or lost. Switch back to the Main input when the signal is re-established may be configured to happen automatically or manually. The 7702BPX-IF occupy one card slot and can be housed in the 1RU 7801FR frame which holds up to four single or two dual slot modules, the 3RU 7800FR frame which has a 15 slot capacity, the portable 3RU 350FR frame which has a 7 slot capacity, or a standalone enclosure which holds a single module.
