摘要

晶体管技术的最新发展使其成为传统电子管放大器的替代品，使放大器更高效，更便宜。本项目设定为在27.12 MHz使用固态放大器的1.5 KW放大器。此外，1.5 kW放大器必须满足智能仓库系统中用于射频加热的串联级联射频功率放大器的要求。对放大器进行了设计、制作和测量，取得了良好的效果。功率放大器采用LDMOS晶体管技术。类操作AB推拉配置为功放级。在相对较低的27.12MHz频率下，放大器采用了不同寻常的设计方法。

Continuous Wave Solid State Power Amplifier For RF Heating System

The latest development in transistor technology has enabled it as a replacement for the traditional electron tube amplifiers, making the amplifiers more efficient and less expensive. This project set out to 1.5 KW Amplifier at 27.12 MHz using solid state amplifier. Moreover, the 1.5 kW Amplifier has to meet the demands of a series cascaded radio frequency power amplifier for RF Heating which is used in smart warehouse system.Amplifier have been designed, fabricated and measured, showing promising results. The power amplifier utilizes a LDMOS transistor technology. Class of operation AB push pull configuration for the power amplifier stage. At relatively low frequency of 27.12MHz amplifier make use of unusual design approaches.
