All supply pins should be bypassed with external capacitors to minimize noise and fast transients. Supply noise can

degrade noise figure and fast transients can trigger ESD clamps and cause them to fail. Supply voltage change or

transients should have a slew rate smaller than 1V/20uS. In addition, all control pins should remain at 0V (+/-0.3V)

while the supply voltage ramps or while it returns to zero.
