ISL5239 Product details
Features
The ISL5239 Pre-Distortion Linearizer (PDL) is a full featured component 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 communication 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 completely linear.
