Switch Configuration

Driving the Switch

Each RF path can be closed by applying ground (TTL "High" for Option T24) to the corresponding
"drive" pin. In general, all other RF paths are simultaneously opened by internal logic. See
Figure 2-1
Figure 2-1
The default operation of the switches is break-before-make. Make-before-break switching can be
accomplished by simultaneously selecting the "drive" pins for old RF path and new RF path. Once
the new RF path is closed (15 ms), de-select the old RF path "drive" pin while leaving the new RF
path "drive" pin selected. The switch circuitry will automatically open the old RF path while leaving
the new RF path engaged.
