A solid-state radio frequency (RF) microwave oven for an aircraft galley is dimensioned to fit the galley and includes within the oven cavity an array of RF modules disposed on the upper interior surface of the cavity. Each RF module includes one or more RF emitters programmable to heat meals placed within the oven cavity by emitting tunable RF signals. The RF modules may monitor the internal temperature and doneness of the food by detecting returned unabsorbed energy. An oven control module (OCM) may communicate with the aircraft galley network, selectively manage the activation and deactivation of RF modules depending on the food being cooked and its changing internal temperature, and tune emitted RF signals to avoid interference with aircraft communication systems. Compact heat sinks may be located within the rear of the oven cavity for the removal of excess energy from the oven.
