Abstract

The paper is devoted to microwave power meters, detector blocks of which can be located directly on the main PC board. The block diagram with dynamic range extension method was shown. Portable PLS series power meters with frequency range from 50 MHz to 6 GHz produced by Micran Company is presented. Galvanic isolation unit is proposed.

Summary

Introduction

Development of modern technology requires improvement of the technology for the provision of information and telecommunication services (satellite communications, television, radio navigation, etc.) using electromagnetic radiation in the microwave range. Power is the main energy parameter for microwave signals [1]. Telecommunication development leads to a complication of the RF signals, the requirements for characteristics of power meters, such as frequency and dynamic ranges, accuracy, and the capability to measure modulated signals, including different digital modulation types and pulse modulation. It’s known few main power sensors types: bolometer, calorimeter, diode detector [2]. Bolometers and calorimeters are characterized by such disadvantages as high inertness, low level of sensitivity, low measurement speed. Advantages of diode detectors: speed, high sensitivity and small size. We consider one of the options for the implementation of microwave power meters with a dynamic range of 70 dB developed and manufactured by Micran research and production company (Tomsk, Russia) [3]
