Abstract
A front end receiver is disclosed. The front end receiver comprises a plurality of transmissive signal paths originating from one signal input, a plurality of switching mechanisms; and at least one path of the plurality of transmissive signal paths including a first amplifier coupled to a first input port of each of the plurality of switching mechanisms. The front end receiver also comprises at least another path of the plurality of transmissive signal paths including a second amplifier coupled to a second input port of each of the plurality of switching mechanisms. The receiving subsystem coupled to the output port of each switching mechanism. Each of the receiving subsystems controls a switching mechanism to select the path that is optimal for radio reception depending on the strength of signal being received.
