Receiving system, radio frequency module and wireless device

摘要

Problem to be solved: to provide a receiver front end system which reduces at least one of out of band noise index or out of band gain of one corresponding path of a plurality of paths corresponding to the multiple frequency band.Receiver system 900 includes a DRX controller 902 which selectively activates one or more of the plurality of paths between the input of the receiving system and the output of the receiving system.The receiving system further includes a plurality of amplifiers 143a-330d.Each of the plurality of amplifiers can be provided along one correspondence path of a plurality of paths and amplifies the received signal in the amplifier.The receiving system further includes a plurality of impedance matching components 934a to 934d.Diagram
