NOTES:
(1). The 50  resistor should be removed if pin 8 is connected to another coupler for daisy chaining multiple couplers.
(2). This capacitance value can be reduced for multi-PA with DC to DC converter applications where a total maximum
capacitive load is required to be met. Keeping at least a 1uF capacitor close to the PA Vcc pin is recommended.
(3). A capacitor of at least 10 nF should be placed closed to the PA VCC pin (pin10) for optimum decoupling.

NOTES:
(1). VCC2S is a sense line to be used if the test power supply has voltage sensing
capability. This compensates for any resistive voltage drop that occurs between
the power supply and the PA and thus ensures that the voltage at the PA is set as
expected.
