Configuringthe RF Switch 17
Chapter 1
Cables and Connectors TheCascade RF Switch module is shipped with a kit of 85 SMB connector
jacks and 10 connector housings. You must s upply your own 50Ω
double-shielded cable (single-shielded cable can also be used ). Agilent
recommends RG188DS or RS316DS double-shielded cables or
triple-shielded cable (part number 8120-0552).
Standard SMB connector jacks will fit into the Cascade RF Switch module
connector sockets and may be used if adjacent sockets on the module are
NOT used. However, the outside diameter of the standard SMB jacks
prohibits using them on the closely spaced, adjacent sockets on the module
and they will not fit in the connector housing. Special jacks with a smaller
shoulder must be used if adjacent sockets on the module are used. See
Table 1-1.
Assembling SMB
Connector Jacks Figure1 -7shows how to assemble the SMB connector jacks. Jacks for
double-shielded cable require a 0.151 hex crimp about 0.260 wide.
Individual jacks for single-shielded RG188 and RG316 cable are available
from E. F. Johnson Co (part number 131-4303-011/020) and require a hex
crimp size of 0.128.
