Zusammenfassung:The proliferation of cellular and personal communication networks burdens an already overcrowded frequency spectrum. These systems require modern RF power amplifiers to maintain high levels of spectral efficiency for minimized adjacent channel interference. Amplifiers must maintain ultra linear transfer functions to achieve spectrally efficient operation. Several amplifier architectures (including feedforward) capable of ultra linear operation are illustrated, compared and analyzed.
