Section 7: Redundant System Configurations

7.0 Redundant System Concepts

The Mini 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 Mini 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 RCP2-1200 controller is required.

7.1 1:1 Redundant Systems

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.
