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.
