Input Back-Off (IPBO): This is the power level at the RF amplifier's input relative to the input power that produces maximum output power. The waveguides can be manufactured directly, either by using the PCB as a substrate or in a separate step, before being laminated with the rest of the stack. This paper investigates the trade-off between power amplifier (PA) nonlinearity, output power backoff (OBO), digital predistortion (DPD), and clipping and filtering (CF) in terms of energy consumption. The energy efficiency of a PA depends on the OBO of the signal and usually increases as the OBO. The main characteristics of an optical power amplifier for a coherent free-space data transmission system are.
