The phase delay for RFOUT1 is altered between 0° and 360°, so that all possible load phases are scanned. The VSWR at the
connection shall be 20:1@0.9GHz, 15:1@1.8GHz. The other outputs, shall be connected to open-circuit (PIN left open) or sig-
nal ground; both options should be tested. After testing RFOUT1, the same test should be done for the other outputs.
