Manufacturing

Dual-band amplifier

Overview

Organization Name

kazuhiko HONJO Advanced Wireless and Communication Research Center (AWCC) The University of Electro-Communications

Details

Key Point

  • It is impossible to reduce distortion in multiband amplifiers using DPD. There is an international project to solve this problem by using 3-D DPD, but it has not been successful so far.

Benefit

Simultaneous multiband amplification does not degrade adjacent channel leakage power, and the load on the DPD (digital predistorter) is extremely low.

Market Application

Carrier aggregation in 5G/6G Power amplifiers for base station sharing
