Solutions has under development. Performance is based on engineering tests. Specifications are

typical. Mechanical outline has been fixed. Engineering samples and/or test data may be available.

Commitment to produce in volume is not guaranteed.

Operation of the MA4SW Series Switches

Operation of the MA4SW series of PIN switches is achieved

by simultaneous application of a negative DC current to the

low loss switching arm J1, J2, or J3, and a 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 + 20mA. 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 diode

switches are ESD, Class 1A sensitive (HBM). Proper ESD

precautions should be taken.
