Operation of the MA4SW 210B-1 and MA4SW310B-1

Operation of the MA4SW210B-1 and MA4SW310B-1 PIN diode switches is achieved by simultaneous

application of DC currents to the bias pads. The required levels for the different states are shown in the tables

below. The control currents should be supplied by constant current sources. The nominal 40Ω - 60Ω pull-up

resistor voltage @ J4 and J5 is usually -1V for –20mA and +20mA for +1V.
