    Abstract: Systems and methods for reducing loading in antenna switch module multiplexing are disclosed. In one aspect, a radio frequency front end includes a plurality of filters configured to filter radio frequency signals, the filters including a first filter configured for single band wireless communication and two second filters configured for multiplexing wireless communication. The radio frequency front end further includes an antenna switch module including a first switch configured to connect an antenna to the first filter for the single band wireless communication, and two second switches configured to connect the antenna to the second filters for the multiplexing wireless communication, the second switches having a lower on-state resistance than the first switch.

    Abstract: A coupler is presented that has high-directivity and low coupling coefficient variation. The coupler includes a first trace with a first edge substantially parallel to a second edge and substantially equal in length to the second edge. The first trace includes a third edge substantially parallel to a fourth edge. The fourth edge is divided into three segments. The outer segments are a first distance from the third edge. The middle segment is a second distance from the third edge. Further, the coupler includes a second trace, which includes a first edge substantially parallel to a second edge and substantially equal in length to the second edge. The second trace includes a third edge substantially parallel to a fourth edge. The fourth edge is divided into three segments. The outer segments are a first distance from the third edge. The middle segment is a second distance from the third edge.

    Abstract: The disclosed front end architectures are configured to conglomerate duplexer transmission (TX) contours into a specific or targeted region. This enables the power amplifier (PA) to match a larger number of frequency bands without the help of additional matching networks. The disclosed architectures are advantageous because they reduce the number of components (e.g., surface mount technology components (SMTs)) required for radio-frequency (RF) modules, such as front end modules, power amplifier modules, and the like. The disclosed architectures are also advantageous because they improve performance of the modules across a wider range of frequency bands.

    Abstract: A switching module assembly is provided. The switching module assembly includes a plurality of transmit/receive terminals, an antenna terminal, a shunt indictor coupled to the antenna terminal, a plurality of duplexers coupled to the plurality of transmit/receive terminals, and a plurality of impedance rotation elements coupled to the plurality of duplexers. Each duplexer corresponds to a signal frequency of a plurality of signal frequencies, and the impedance rotation elements are configured to adjust the impedance of each duplexer in conjunction with the shunt inductor to provide a resonant frequency at the signal frequency of each duplexer. The switching module can be used in the front-end module of a communications device, such as a mobile phone.
