This Application Note describes how to use the

M/A-COM DR65-0109 Single Channel Driver for

FET Switches as a SP2T PIN Diode Driver. When

configured per the directions herein, the DR65-0109

will provide the same functionality as the DR65-0003

in the same package style, HOWEVER THE

PINOUT IS DIFFERENT. USING THE DR65-0109
