Key RF specifications include voltage standing wave ratio (VSWR) under 1.2 and insertion loss (IL) of less than 0.14 decibels (dB) from DC to 12.4 GHz, with corresponding VSWR and IL numbers of 1.4 and 0.2 dB from 12.4 to 18 GHz. • SMB: Connectors in the SMB series are designed for snap- on coupling with broadband capability from DC up to 4 GHz. They are smaller than SMA series connectors and thus are well suited for circuit miniaturization. Among the available SMB connectors are pc board receptacles for through- hole and surface mount, as well as edge card and cable connectors for plugs and jacks (Figure 4).
