Abstract
An integrated front-end module (FEM) includes at least one power amplifier (PA) coupled to an antenna without inclusion of a switching element in a transmit signal path in the FEM between an output of the PA and the antenna. The FEM further includes at least one low-noise amplifier (LNA) and a switching circuit coupled in a receive signal path of the FEM between the antenna and an input of the LNA. The switching circuit is configured in a first mode to disable the PA and to connect the input of the LNA to the antenna for receiving signals from the antenna. The switching circuit is configured in a second mode to disconnect the input of the LNA from the antenna and to enable the PA for transmitting signals to the antenna.
