Abstract
An oven includes a cooking chamber configured to receive a load and an RF heating system configured to provide RF energy into the cooking chamber using solid state electronic components. The solid state electronic components include power amplifier electronics configured to provide a signal into the cooking chamber via an antenna assembly. The power amplifier electronics include at least a first power amplifier and a second power amplifier operably coupled to the cooking chamber by respective ones of a first antenna and second antenna of the antenna assembly. The first and second antennas are operably coupled to respective ones of the first and second power amplifiers via a first coupling structure and a second coupling structure, respectively. A directional coupler provided at a port section defined for at least one of the first and second coupling structures. The directional coupler is configured to provide a forward wave parameter and a reflected wave parameter to a measurement assembly configured to calculate modified S parameters at the port section.
