Abstract: A wireless device is described. The wireless device includes an antenna. The wireless device also includes a hybrid transformer. The wireless device further includes a frequency matching termination port. The frequency matching termination port provides impedance matching with the antenna at multiple frequencies. The frequency matching termination port may include multiple resistors, inductors and capacitors that can be switched in/out.

Abstract: Exemplary embodiments are directed to systems, devices, and methods for mitigating effects of transmit signal leakage. A transceiver may include a transmitter and a receiver. The transceiver may further include a multi-tap analog adaptive filter coupled to each of the transmitter and the receiver and configured to generate an estimated transmit leakage signal based on at least a portion of a transmit signal from the transmitter and an error signal from the receiver.
