目前在食品工业领域中涉及新产品开发、食品包装、微波食品加工、、MW 食品测试、 MW 烤炉设计和测试、新材料研究、MW 和RF 相关应用等,而在研究开发过程中对重要参数—— 温度及压力的测量一直是个难题,具调查了解国内现阶段大都采用热电偶或红外测温仪测量温 度,由于热电偶容易受电磁、微波、射频等干扰,所以不能实现时实测量,采集的温度数据可用 性不高,而红外测量虽然能时实测量,但是它是非接触测量受很多因素干扰(特别是水蒸汽), 而且测量精度也不满足研究要求,所以两种方法都不能很好的解决温度测量问题,给研究工作带 来很多不便。 加拿大Opsens公司的光纤传感器很好地解决了温度及压力测量问题,Opsens传感器完全抗电磁、 微波、射频等干扰,多通道在线时实监测微波中食物内、外各个部位温度差异与变化,给研究食 物在不同温度下的成分及含量提供可靠准确的数据,同时通过RS232与计算机连接由软件控制可 以很直观地观察温度、压力曲线变化。

Abstract: This application note describes system-level characterization and modeling techniques for radio frequency (RF) and microwavesubsystem components. It illustrates their use in a mixed-signal, mixed-mode system-level simulation. The simulation uses an RF transmitterwith digital predistortion (DPD) as an example system. Details of this complex system and performance data are presented.

Radio frequency (RF) can be a complex subject to navigate, but it does not have to be. If you are just getting started with radios or maybe you cannot find that old reference book about antenna aperture, this guide can help. It is intended to provide a basic understanding of RF technology, as well act as a quick reference for those who “know their stuff” but may be looking to brush up on that one niche term that they never quite understood. This document is also a useful reference for Maxim’s products and data sheets, an index to deeper analysis found in our application notes, and a general reference for all things RF.
