摘要： Aspects of the disclosure relate to wireless communication, and high-frequency filters with resonators. One example is a frequency band filter circuit having a split resonator. The split resonator comprises a resonator including a first section of a shared input busbar (722), a first section of a shared output busbar (724), and an electrode structure between the first section of the shared input busbar and the first section of the shared output busbar, the electrode structure configured for a resonance. The split resonator also comprises a detuned resonator. The detuned resonator includes a second section of the shared input busbar, a second section of the shared output busbar, and a detuned electrode structure between the second section of the shared input busbar and the second section of the shared output busbar, the detuned electrode structure configured for a detuned resonance different from the resonance.

摘要： 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.

摘要： An integrated circuit chip implementing multiplication of an MxN element matrix with an N-element vector to obtain an M-element product by combining the vector with rows of bits of the same significance selected from the matrix one bit-row at a time to form partial products, exploiting the fact that the same potential combinations are needed for all bit-rows and all matrix rows to precompute all of the combinations once and for all, and combining selected partial products for different bit place-significance with a shift-and-add operation only once for each of the M product elements, thereby effectively using only M multiply-equivalent structures. An N-point Complex Fourier Transform can therefore be claimed which only needs 2N real multiplies and the product of an NxN matrix with another NxN matrix requires only N2 multiplies.
