Microwave Techniques manufactures waveguide auto-tuners with industry-leading technology for high-power microwave and RF applications. These compact devices bring a new level of reliability, efficiency, and intelligence to industrial microwave processing applications with real-time control and data monitoring.

EH Style Waveguide Auto-Tuner, WR975, 915 MHz
The WR975 EH Style Waveguide Auto-Tuner builds on decades of high-power RF design experience to provide a solution capable of continuously tuning out a 10:1 mismatch at any reflection phase, under full 100 kW power conditions. This device, which is superior to any other device in the industry, utilizes standard components and a simple electronic control system, fully integrated into the unit.
There is continuous monitoring of power, frequency, and load impedance. Also, the data logging capability built in provides the operator with a means to characterize applicator RF behavior under varying conditions.
