Chapter 1. INTRODUCTION

The CRS-180 IF 1:1 Switch Module is an IF Tx-Rx signal switch designed for use with

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 switch uses power dividers to provide both

demodulators with the same IF signal from the LNB, thus reducing switching time.

The CRS-180 is designed to support 1:1 redundancy for Comtech EF Data CDM-570

modems. Table 1 summarizes the applications including requirements for supporting data

switching hardware and software.
