摘要： A wireless communication circuit and a transport device for sending rescue message are provided. The wireless communication circuit is arranged in a transport device for sending a rescue message to a cellular network and includes a radio transceiver, a signal amplifier circuit, a plurality of filters, and a first switch. The radio transceiver converts a baseband signal to a radio frequency signal and determines whether the cellular network has been connected. The first switch includes an input end and a plurality of output ends, and is electrically connected between the signal amplifier circuit and the plurality of filters. The first switch connects the input end and one of the plurality of output ends in sequence until the radio transceiver determines the cellular network has been connected. The wireless radio transceiver sends the rescue message through the first switch.

摘要： A signal processing device is provided. The signal processing device includes a proximal end device, a connection unit, and a distal end device. The proximal end device generates a first radio frequency signal. The connection unit is coupled to the proximal end device and receives and transmits the first radio frequency signal. The distal end device is coupled to the connection unit, receives the first radio frequency signal, performs a power detection on the first radio frequency signal to generate a detection signal, generates a control signal according to a comparison result of the detection signal and a predetermined reference value, and transmits the control signal to the connection unit. The proximal end device further receives the control signal through the connection unit, and adjusts the first radio frequency signal according to the control signal so as to generate a second radio frequency signal.

摘要： A tunable antenna module includes a ground metal plane, a nonconductive support element, a first radiation metal element, a second radiation metal element, a switch element, and a plurality of impedance elements. The ground metal plane provides a ground voltage. The first radiation metal element is coupled to a signal source. The second radiation metal element is adjacent to and separate from the first radiation metal element. The switch element selects one of the impedance elements, such that the second radiation metal element is coupled through the selected impedance element to the ground voltage. The nonconductive support element has a 3D (Three-Dimensional) structure. The first radiation metal element and the second radiation metal element are distributed over the nonconductive support element.
