Operation of the MA4SW Series
Operation of the MA4SW series of PIN Switches is
achieved by simultaneous application of negative DC
current to the low loss switching arm J1, J2, or J3, and
positive DC current to the remaining switching arms as
shown in the Bias Connection circuits. DC return is
achieved via J1. The control currents should be supplied
by constant current sources. The voltages at these points
will not exceed + 1.5 volts (1.2 volts typical) at currents up
to + 50 mA. In the Low Loss state, the series diode must
be forward biased and the shunt diode reverse biased. In
the isolated arm, the shunt diode is forward biased and the
series diode is reverse biased.

Handling Considerations
Cleanliness: These chips should be handled in a clean
environment.
Electro-Static Sensitivity: The MA4SW Series PIN
switches are ESD, Class 1 sensitive. The proper ESD
handling procedures should be used.
