Pre-Distortion Linearizer
Features
The ISL5239 Pre-Distortion Linearizer (PDL) is a full featured ponent for Power Amplifier (PA) linearization to improve PA power efficiency and reduce PA cost.
The Radio Frequency (RF) PA is one of the most expensive and power-consuming devices in any wireless munication system. The ideal RF PA would have an entirely linear relationship between input and output, expressed as a simple gain which applies at all power levels. Unfortunately, realizable RF amplifiers are not pletely...
