| Abstract: | According to the linearization requirements of millimeter wave PA,anti parallel Schottky diodes are used to design a millimeter wave linearizer.Its basic structure and working principle are introduced.The circuit is optimized and simulated by software.Based on the simulation,the linearizer is applied to a power amplifier.The test results show that the IM3 has been improved by more than 8 dB.The results show that this linearizer has simple structure,and can be easily adjusted.It is of practical valuable. |
