DWM1000 using PA/LNA

Hi everyone,
we’re researching the usage of PA/LNA with DWM1000,
but there is a problem that when we use large gain PA&LNA,
the received power might be saturated when tag and anchor are close.
Is there anyway to solve this? because we’re going to make sure the application
works fine in both near and far range.
Is there any function of DWM1000 (such as GPIO pins) can deal with power saturation?

By the way, APS004 and APS009 show that PA/LNA should be connected to GPIO5/6 and with an inverter,
we consider the idle mode and use both GPIO5 and GPIO6 without an inverter, is it OK?
