Wideband RF power meterwith frequency range up to 10 GHz

Radio frequency (RF) power meter is useful device for design of wireless communication systems and for many other applications. It is important device for RF design engineers in order to measure the level (strength) of electromagnetic (EM) field at any point from transmitter. For example, using RF meter, we can check if the EM field is below the specific allowed level for human health. Moreover, we can use it in test area at far-field region after installing the antenna and transmitter. In this paper, wideband RF power meter is designed based on hardware and software with ability to measure any RF signal in frequency range 0-10 GHz. It is a portable RF meter with small size. Moreover, it has LCD, LEDs bar as a display options, and buzzer as an alarm when the signal level exceeds specific threshold.
