求翻译：射频功放的效率和线性度是一对矛盾，如何寻找一个折中点使射频功放保持高线性的同时，具有高效率，是近年来国内外学者研究的热点。是什么意思？

RF power amplifier efficiency and linearity is a contradiction, how to find a compromise point of the RF power amplifier, while maintaining high linearity, high efficiency, is a hot research in recent years, scholars at home and abroad.

RF amplifier efficiency and linearity are a pair of contradictions, how to find a compromise between the RF amplifier is maintaining the high linear, highly efficient and is at home and abroad in recent years scholars research hot.

The radio frequency merit puts the efficiency and the linearity are pair of contradictory, how seeks a compromise spot to cause the radio frequency merit to put maintains high linear at the same time, has the high efficiency, is hot spot which the recent years domestic and foreign scholars studied.

Degree of efficiency and linear RF power amplifier is a rightness of Antinomies, how about looking for a break point while maintaining high linearity RF power amplifiers, with high efficiency, in recent years scholars study hotspots at home and abroad.
