  • Reducing harmonic leakage in wireless communications using switching
    Patent number: 10848187
    Abstract: Disclosed herein are wireless transceivers with switches to reduce harmonic leakage. The devices are configured to transmit and receive signals in a first frequency band and a second frequency band. The devices selectively decouple a power amplifier from a duplexer to reduce harmonic leakage into a receiving system. The decoupling is accomplished using a switch, the switch being operated responsive to a band select signal indicating the second frequency band as a receive band but not a transmission band and the first frequency band as a transmission band where the first frequency band has at least one harmonic that lies within a downlink sub-band of the second frequency band.

  • Wireless transceiver with switch to reduce harmonic leakage
    Patent number: 10284235
    Abstract: Disclosed herein are wireless transceivers with switches to reduce harmonic leakage. In some embodiments, a transmitter system includes a power amplification system including a first power amplifier configured to amplify a signal at a first cellular frequency band and a second power amplifier configured to amplify a signal at a second cellular frequency band. The transmitter includes a switch coupled between an output of the second power amplifier and a ground potential. The transmitter includes a controller configured to, based on a band select signal, control the switch and selectively enable or disable each of the first power amplifier and the second power amplifier. Selective control of the switch can reduce harmonic leakage compared to a system that does not include the disclosed switches and controls.
