Operating Instructions
Operator’s check
The operator's check allows the operator to make a quick check of the solid state
switches prior to use or if a failure is suspected.
Description
The solid state switch is connected to a network analyzer configured for the
S-parameter measurement. The network analyzer may be set to sweep over the
whole or selected frequency range of the solid state switch to be verified. The S
21
(insertion loss) measurement is the best way to determine if the switch is faulty by
applying the appropriate logic to the CTRL pin.

CAUTION
The RF port center conductors connect directly to the GaAs MMIC and are
thus sensitive to electrostatic discharge (ESD). ESD exceeding the level
specified in “Environmental Conditions” on page 3 or RF power applied is
greater than the maximum specified in Table 2-2 may cause permanent
damage to the device.
