DW1000 PA chip time parameters

Hello, we have a research project recently and want to build DW1000-based equipment with a distance measuring distance of 5 kilometers. There are several problems as follows:

  1. What is the switch response speed requirement of the PA chip?
  2. What is the difference between the 33 and 34 pins of the DW1000 chip, and which one should be used to control the PA chip switch.
  3. Is the time parameter of the power amplifier control signal output by the DW1000 chip adjustable (pre-opening time and delayed closing time)
