MA4SW410B-1
HMIC™ Silicon SP4T PIN Diode Switch
with Integrated Bias Network
Rev. V4
Operation of the MA4SW410B-1 PIN Switch
Operation of the HMIC Series of PIN switches is achieved by the simultaneous application of negative DC current
to the low loss port and positive DC current to the remaining isolated switching ports per the Driver Connections
table below. The control currents should be supplied by constant current sources. For insertion loss, -10 mA bias
results in approximately -2 V, and for Isolation,+10 mA yields approximately +0.9 V at the respective bias nodes.
The backside area of the die is the RF and DC return ground plane.
