Abstract
A transceiver having an antenna-connection port and an FEM-connection port is disclosed. Exemplary embodiments provide a transceiver having an antenna-connection port and an FEM-connection port that may support a connection to an external FEM and also support a connection to an antenna without a separate RF switch when an antenna is used without an FEM.
Claims8
A transceiver, comprising:
- an input/output common port (Rx/Tx Port) configured to receive an Rx signal or to output a Tx signal by connecting to an antenna (ANT), or to output the Tx signal by connecting to a Tx input terminal of a front-end module (FEM);
- an input only port (Rx Port) configured to receive the Rx signal by connecting to an Rx output port of the FEM;
- a low-noise amplifier (LNA) configured to form a plurality of Rx paths by connecting to the input/output common port and the input only port respectively, and configured to amplify and output the Rx signal after receiving the Rx signal using the plurality of Rx paths;
- a power amplifier (PA) configured to form a Tx path by connecting to the input/output common port, and configured to apply the Tx signal to the input/output common port using the Tx path;
- and
- a plurality of switching devices configured to form the Tx path and the plurality of Rx paths by performing switching between the PA and the LNA and between the input/output common port and the input only port respectively.
