HMIC™ Silicon PIN Diode Switches

RoHS Compliant

Operation of the MA4SW Series Switches

The simultaneous application of a negative DC current to the

low loss port and positive DC current to the isolated port is

required for proper operation of the MA4SW series of PIN

switches. The backside area of the die is the RF and DC

ground return and the DC return is through the common Port

J1. A constant current source should be used to supply the

DC control currents. The control voltages at these points will

not exceed ±1.5 volts for supply currents up to + 20mA. In

the low loss state, the series diode must be forward biased

and the shunt diode reverse biased. On all isolated ports, the

shunt diode is forward biased and the series diode is reverse

biased.
