Abstract: An apparatus for interference cancellation in wireless communication systems configured for reception, comprises a receive signal path configured to convey an overall receive (Rx) signal comprising an Rx signal and a residual transmit (Tx) signal, from an antenna port to an Rx input port of a transceiver, and at least one cancellation path configured to receive a leakage Tx signal from the antenna port. Further, the apparatus comprises a cancellation unit configured to apply a cancellation signal to the overall Rx signal in the receive signal path and a compensation unit configured to generate the cancellation signal by modifying the leakage Tx signal in the cancellation path, based on a compensation control signal. In addition, the apparatus comprises a feedback receiver unit configured to generate the compensation control signal based on the residual Tx signal in the overall Rx signal and the cancellation signal.

Abstract: Techniques are provided for reducing or mitigating phase noise of a digital phase lock loop or the system depending on the digital phase lock loop. In an example, a multiple-mode digital phase lock loop can include a digital phase lock loop (DPLL), multiple frequency scalers configured to receive a reference clock, and a multiplexer configured to receive a mode command signal and to couple an output of one of the multiple frequency scalers to an input of the DPLL in response to a state of the mode command signal.

Abstract: Embodiments of front-end module (FEM) circuitry and a communication device are generally described herein. In some embodiments, the FEM circuitry may be configured to provide uplink (UL) multiple-input multiple-output (MIMO) signals and/or UL carrier aggregation (CA) signals for transmission by the communication device. The FEM circuitry may comprise a hybrid coupler to generate a first antenna transmit signal and a second antenna transmit signal. The FEM circuitry may further comprise one or more tunable phase shifters. In some embodiments, the phase shifters may phase-shift a first radio frequency (RF) signal and a second RF signal according to a 90 degree phase difference to generate the hybrid coupler input signals. Accordingly, the antenna transmit signals may be transmitted according to the UL-MIMO configuration.

Abstract: An apparatus for interference cancellation in a wireless communication system, includes a cancellation unit configured to receive a transmit (Tx) signal from an output port of a power amplifier and a receive (Rx) signal from an antenna, and generate a cancellation of a primary portion of the Tx signal from the Rx signal at an output thereof, leaving a residual portion as a residual Tx signal, wherein the output of the cancellation unit is coupled to an Rx input port of a transceiver. The apparatus further includes a compensation control unit configured to modify one or more signals within the cancellation unit, based on the residual Tx signal at the output of the cancellation unit.

Abstract: A tunable transformer based duplexer (TTBD) comprising a first antenna port and a second antenna port. The TTBD further comprises a first winding coupled between a transmitting port and the first antenna port, wherein the first antenna port is configured to receive a first signal; a second winding coupled between the transmitting port and the second antenna port, wherein the second antenna port is configured to receive a second signal. Further, the TTBD comprises a receiving amplifier comprising at least one input and at least one output. The TTBD also comprises a third winding comprising a first terminal and a second terminal. The third winding comprises a first inductance and is coupled to the at least one output of the amplifier circuit. A first coupling is formed between the first winding and the third winding and a second coupling is formed between the second winding and the third winding. The TTBD further comprises a tunable capacitance coupled between the first terminal and the second terminal of the third winding. The tunable capacitance and the first inductance together form a band-pass filter.
