What is the MAX2871 output power at 5.8GHz?

Bench Test Results:
Using the MAX2871 EVKIT, the output power at room temperature is -4.09dBm.  This measurement was taken from RF_OUTA+ with RF_OUTA- terminated with a 50ohm pad.  The output was pulled up to VCC with a 50ohm resistor, and the 3dB pad was installed.  So, the actual output power will be closer to -1.09dBm.  The following register setting were used:

Reg 0: 003A0000
Reg 1: 400103E9
Reg 2: 80005F42
Reg 3: 00001F23
Reg 4: 638E80FC
Reg 5: 00400005
Reg 6: 00000006
