3.2.3 System Component Installation and Interconnection
Refer to Figure 3‐1 through Figure 3‐3 to follow these steps:
Step Task
1
Install the SSPAs in their respective positions as detailed in the factory datasheet and in accordance with
Figure 3-1. This means that the specific serial numbered SSPA that was aligned in Position 1 at the factory
must also now be 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.
2
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 waveguide gaskets at each
SSPA 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-4000 Phase Combiner Control Box (PCCB) to the mounting structure.
4
Install the Type ‘N’ RF Phase Matched Coaxial Cables (CEFD P/N CA/RF11872-1) as shown in Figure 3-3.
Each cable is labeled according to its destination SSPA:
o
Connect the cable labeled “SSPA1” from the PCCB Type ‘N’ port labeled “SSPA OUT 1 | J9” to the
RF Input port on SSPA #1.
o
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.
5
Install the “COM” Cable (CEFD P/N CA/WR11966-2) between each of the following PCCB connectors and their
corresponding SSPA “COM” ports:
o
(PCCB) “SSPA COM 1 | J2” to SSPA #1.
o
(PCCB) “SSPA COM 2 | J3” to SSPA #2.
6
Install a Waveguide (WG) Switch Control “Y” Cable (CEFD P/N CA/WR12013-1) between the PCCB connector
labeled “SSPA SW OUT | J5” (Figure 3-3) and the two waveguide switches as shown in Figure 3-1. Pay
particular attention to ensure that the ends labeled “SW1” and “SW2” are connected, respectively, to
Waveguide Switch #1 and Waveguide Switch #2.
7
Install the user-provided RF Input Switch control cable (if applicable) to the PCCB connector labeled “RF INPUT
SWITCH | J6”.
8
Properly terminate the waveguide system output port, review all cables for proper connections, and ensure
that all mounting hardware is tightened.
