Abstract
A system for suppressing transmission channel noise in a signal transmission/reception device—particularly a time division duplex (TDD) wireless communications device—is provided. The system provides one or more shunt elements, instantiated at some point along the device's signal transmission channel. One or more attenuation elements are also instantiated at some point along the signal transmission channel, as are one or more disabling elements. A trigger signal indicates when the device is shifting from signal transmission operation (or mode) to signal reception operation. Responsive to assertion of the trigger signal, the shunt, attenuation and disabling elements are activated.
