Agilent Technologies E1470A Assembling SMB Connector Jacks, SMB Connectors and Connector Housings

Cables and Connectors The Cascade RF Switch module is shipped with a kit of 85 SMB connector jacks and 10 connector housings. You must supply 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.

*Single SMB jacks are available from E. F. Johnson Co. by part number 131-4304-011/020.

Assembling SMB Connector Jacks

Figure 1-7 shows 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.
