Abstract: A system for measuring a temperature of a food in an oven includes an energy emitting antenna positioned in the oven proximate an oven cavity and a battery-free sensor probe configured to be inserted into the food in the oven cavity. The energy emitting antenna sends a plurality of first signals at a same frequency that are phase shifted relative to each other. The battery-free sensor probe has a sensor probe antenna harvesting energy transmitted from the energy emitting antenna and transmitting a plurality of second signals back to the energy emitting antenna. The first signals are steered by the phase shifting to ensure that the first signals are received by the sensor probe antenna.

Abstract: A radio frequency (RF) heating apparatus and a microwave oven including an RF heating apparatus. The apparatus includes a cavity for receiving an object to be heated. The apparatus also includes a plurality of channels for generating RF radiation to be introduced into the cavity. Each channel includes a frequency synthesizer, a power amplifier and an antenna. Each channel is operable to use a common phase reference signal for generating the RF radiation. Each channel may be controllably operable to generate RF radiation having different, respective frequency spectra. Forward and reverse signal detection circuitry may be provided that is operable to determine amplitude, frequency and/or phase information relating to RF radiation in the cavity. This information may be used for adaptively controlling the RF radiation generated by each channel.

Abstract: An outphasing amplifier having: a first branch arranged to receive and process a first branch signal, the first branch signal being phase modulated, with constant amplitude envelope; and a second branch arranged to receive and process a second branch signal, the second branch signal being phase modulated, with constant amplitude envelope, and at least a portion of the second branch signal anti-phase from the first branch signal, wherein each branch includes: circuitry arranged to process the signal to reduce the energy in sidebands of the signal away from the central frequency, while retaining the phase information in the signal; and an amplifier arranged to amplify the filtered and re-asserted branch signal.
