Find the block in the schematic or trace the board where RF exits before the antenna port. 2. Locate the PA input point – The PA usually has a small matching network (caps/inductors) at its input. This is where the signal chain feeds it. 3. Disconnect original signal chain – To repurpose, you bypass mixers/filters and feed your own RF into the PA
