Max output power when operating at 1.8V?

[KHoll]

To achieve the +6dBm output power on the WB55, VDD needs to be > 1.95V. What is the max ouput power you can achieve if the device is operated at 1.8V?

[Remi QUINTIN]

With SMPS ON,  it is required to have VDD > 1V95 to get Pmax = 6dBm.

But with SMPS BYPASS, Pmax = 6 dBm can be achieved with only VDD > 1V71.

We did not test the configuration you ask for: SMPS ON with VDD = 1V8.
