Hi, I referred to the data sheet. The data sheet says that programmable output power range is -24 to 0 dBm (in steps of 3). There is no mention about reverse link gain. Do we have straightaway assume that it is less than that of tx ?
How do I model reverse gain ? I am a bit confused. Any help is appreciated.
