World band radio frequency front end module, system and method thereof

摘要

The present disclosure relates to a World Band Radio Frequency Power Amplifier and a World Band Radio Frequency Front End Module. The World Band Power Amplifier can contain at least one broadband power amplifier connected to a switch which can direct an RF input signal to a plurality of transmission paths, each transmission path configured for a different frequency. The World Band RFFE Module is more integrated version of the World Band Power Amplifier that can contain broadband RF PA(s), switches, logic controls, filters, duplexers and other active and passive components.

主权项

1. An integrated module for use in a radio frequency (RF) front end system comprising:
a first RF signal input to a first switch module including frequencies in the range of 698 to 915 MHz or 1.7 to 2.1 GigaHertz (GHz), wherein the first switch module is connected to a first broadband power amplifier configured to amplify frequencies in the range of 698 to 915 MHz and a second broadband power amplifier configured to amplify frequencies in the range of 1.7 to 2.1 GHz; a second switch module connected to the first and second broadband power amplifiers, wherein said second switch module is a multi pole, multi throw switch containing a plurality of switches which are selectively operable to couple the first RF signal input to one of a plurality of transmission paths, each of said transmission paths configured to transmit a plurality of different frequency bands; a plurality of filters connected to the outputs of the second switch module and configured to filter transmission path signals; a third switch module coupled to the plurality of filters and capable of outputting a plurality of frequencies greater than 698 MHz; and a second RF signal input to a third broadband power amplifier which is parallel to the first and second broadband power amplifiers and which operates substantially in the range of 4.9 GHz to 6 GHz.
