Abstract: A multiway switch, a radio frequency system, and a wireless communication device are provided. The multiway switch includes six T ports and 2 n P ports. The six T ports include two first T ports and each of the two first T ports is coupled with all of the 2 n P ports. n is an integer and n ≥2. The multiway switch is configured to be coupled with a radio frequency circuit and an antenna system of a wireless communication device operable in a dual-frequency single-transmit mode, to implement a preset function of the wireless communication device. The antenna system includes 2 n antennas corresponding to the 2 n P ports. The preset function is a function of transmitting a sounding reference signal (SRS) through the 2 n antennas in turn.

Abstract: A multiway switch, a radio frequency system, and a wireless communication device are provided. The multiway switch is applicable to a wireless communication device being operable in a single-frequency single-transmit mode. The multiway switch includes five T ports and 2 n P ports. The five T ports are configured to be coupled with a radio frequency circuit. The 2 n P ports are configured to be coupled with an antenna system comprising 2 n antennas. The five T ports include one first T port coupled with all of the 2 n P ports. The multiway switch is configured to be coupled with the radio frequency circuit and the antenna system to implement a preset function of the wireless communication device of transmitting a sounding reference signal (SRS) through 2 n antennas corresponding to the 2 n P ports in turn. A function of transmitting an SRS through four antennas corresponding to 2 n ports in turn (that is, 2 n -port SRS) of an electronic device in the fifth generation new radio (5G NR) is implemented.

Abstract: Aspects of the disclosure relate to devices, wireless communication apparatuses, methods, and circuitry for a t-switch with gate shunting. One aspect is an apparatus including a first differential switch having a control input. The apparatus further includes a second differential switch coupled to the first differential switch, the second differential switch a control input. A shunt capacitor is coupled between a first output and a second output of the first differential switch, and a first input and a second input of the second differential switch. A first shunt switch having a control input, an input, and an output has the input and the output coupled to the control input of the first differential switch. A second shunt switch having a control input, an input, and an output, has the input and the output coupled to the control input of the second differential switch.

Abstract: A signal up-conversion system is described. The system comprises a signal input for receiving an input signal to be up-converted; an oscillator system for generating an up- conversion signal having a selectable frequency; a mixer coupled to the input and to the oscillator, for combining the input signal and the up-conversion signal and to generate an up-converted signal; at least two filters, each of the at least two filters having different filtering characteristics; a signal output; a switch system configured to couple one of the at least two filters into a signal path between the output of the mixer and the signal output; and a controller configured to control a frequency of the up-conversion signal and a filter of the at least two filters coupled into the signal path by the switch system. A method switching between up-conversion frequencies is also described.
