System Component Installation and Interconnection
Refer to Figure 3-1 through Figure 3-3 to perform the follow these steps:
Step
Install the SSPAs in their respective positions as detailed in the factory datasheet and in accordance with
Figure 3-1. The specific serial numbered SSPA that was aligned in Position 1 at the factory must also now be
1
installed in Position 1; the same applies to the SSPA in Position 2. Refer to cable and component labeling to
assure correct installation. It is suggested that any mounting hardware used in the installation process not be
fully tightened until the entire system is installed.
Attach the Waveguide (WG) combining network to the mounting structure and to each SSPA. For assembly
details, see Appendix A. ASSEMBLY KITS. Take care to install the provided WG gaskets at each SSPA
2
output. It may be necessary to slightly adjust each SSPA to prevent undue stress on the waveguide structure.
Tighten all hardware when proper alignment is achieved.
3
Assemble the PCB-4000A PCCB to the mounting structure.
Install the Type 'N' RF Phase Matched Coaxial Cables (CEFD P/N CA/RF11872-1). Each cable is labeled
according to its destination SSPA:

Operation and Adjustment Procedures
Figure 3-4. PCB-4000A – Left Side
Connect the cable labeled "SSPA1" from the PCCB Type 'N' port labeled "SSPA OUT 1 | J9" to the
RF Input port on SSPA #1.
Repeat this task for the cable labeled "SSPA2", connecting it between the PCCB Type 'N' port
labeled "SSPA OUT 1 | J10" and the RF Input port on SSPA #2.
Make sure to correctly install all RF cabling, as any "cross" connections will cause system
malfunction.
