Model power amplifier with memory

**Library:**RF Blockset / Circuit Envelope / Elements

The Power Amplifier block models two-terminal power amplifiers. A memory polynomial expression derived from the Volterra series models the nonlinear relationship between input and output signals. This power amplifier includes memory effects because the output response depends on the current input signal as well as the input signal at preceding times. These power amplifiers are useful while transmitting wideband or narrowband signals.
