DESIGN AND CONSTRUTION OF A DUAL SENSOR RF POWER-METER

Abstract

The drive for globalization has made the need for effective and efficient spread of information inevitable. This has prompted the mounting demand for fast and cost effective means of internet connectivity, in turn placing more demand on the radio (microwave radio) engineers and radio armatures, whose work is no longer limited to handling low range frequency equipments such as TV and radio transmitters. The radio engineer today is bound to use equipments radiating RF signals in the GHz range which requires proper radio planning for maximum utilization of equipment capacity. Thus, the need for a cost effective RF Power-Meter, capable of measuring the power of RF signals is unavoidable. This project explores the use of two sensors; a Diode Sensor and a Thennal Sensor to realize the construction of a dual sensor microcontroller based RF Power-Meter meant to measure the strength of RF signal of frequency as high as 2.4GHz.
