MA4SWx10 Series
HMIC™ Silicon PIN Diode Switches
Operation of 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 +50mA. In the low loss state, the se-
ries 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.
