Innovative Passives and Substrates Enable RF Power Amplifier Designs for Cooking Applications

Solid state RF power amplifiers offers major benefits in performance of microwave ovens vs. magnetron technology, by improving heating distribution profiles and extending the life of the equipment with improved efficiencies. In addition, the power efficiency allows for significant savings in power consumption. To do so, advances in passive components and substrates are aiding in the adoption of this new exciting technology. In this webinar, we will cover approaches by industry leading companies like Huber & Suhner, Anaren and Rogers Corp in the area of connectors, matching components, sampling couplers and substrates that provide solid state alternative paths to waveguides and magnetrons in cooking devices.
