Abstract
The present disclosure provides a radio frequency detecting device, a detecting method, and a microwave oven, and the radio frequency detecting device comprises: a signal transmitting device configured to generate and transmit multiple forward frequency detecting signals of different frequencies; a signal receiver configured to receive multiple reverse frequency detecting signals reflected by the load; a first detection device configured to detect each first parameter corresponding to each of the forward frequency detecting signals; a second detection device configured to detect each second parameter of each of the reverse frequency detecting signals; and a microcontroller configured to determine a state parameter of the load based on the multiple frequencies and the first parameter and the second parameter corresponding to each of the frequencies.
