•
1:2PhComb – This mode is similar to 1:2 mode, but is used to combine two
SSPA outputs rather than supplying a signal for two separate polarizations. Use
of N+1 controls in conjunction is highly recommended. See 1:2 Phase com-
bined operation section for details.
•
SinglSw – This SSPA mode allows the control of a maintenance switch con-
nected to the output of single SSPA unit. This is not a redundancy operation
mode. The switch is used to redirect the output of an SSPA between an anten-
na and a dummy load. See Maintenance Switch Operation section for details.

the amount of attenuation will be affected. See Section 3.6.6.3 .
