    Tx-Rx IF signal switch designed for use with Comtech EF Data IF satellite modems in a 1:1 configuration. The Tx side switches the Online unit onto the transmit coaxial cable. The Rx side of the CRS-180 uses power dividers to provide both demodulators with the same IF signal from the LNB, thus reducing switching time.

    Fourth, +12V is routed from each modem to the CRS-180 for operational power. This power • from both modems is diode OR’d so that the CRS-180 remains active if power is lost from one of the modems. IF Switching – The CRS-180 provides IF redundancy, but when switching occurs, it accommodates more than just the IF signals.

With the ‘bridging’ architecture of the CRS-180 (whereby identical terrestrial data traffic signals are routed to both Online and Offline modems), the redundancy controller can avoid unnecessary switchovers.
