The Compact Outdoor Amplifier is capable of operating in a variety of redundant system 
configurations. These include 1:1 and 1:2 as well as 1:1 with L-Band Block Up Converters. 
The Compact Outdoor Amplifier has a built-in 1:1 redundancy controller, allowing it to be used 
in 1:1 redundant systems without a separate external controller. When used in a 1:2 
redundant system a separate controller, RCP2-1200, is required.   The three most common 
forms of 1:1 redundant system are shown in Figures 7-1 through 7-3. 

Figure 7-1 shows a standard 1:1 system in which the RF input is transmitted through a 
transfer switch along with the output. Using this configuration the standby amplifier carries no 
traffic and simply is terminated by a 50 ohm resistive load at its input and by a waveguide 
termination at its output.   

 
With the system configured as in Figure 7-2, the RF input is passed through a microwave 
splitter. This keeps ‘live’ traffic on the standby amplifier and is useful for observing the traffic 
via the RF sample port on the standby amplifier.
