World band frequency front end module, system and method thereof
First Claim
1. A method of protecting a first broadband power amplifier in an integrated broadband power amplifier module by disabling operation of the first broadband power amplifier at a predetermined temperature:
- amplifying a first radio frequency (RF) signal using the first broadband power amplifier;
sensing the temperature inside the broadband power amplifier module using a first temperature sensor;
enabling and disabling operation of the first broadband power amplifier based on the output of the first temperature sensor; and
a second broadband power amplifier capable of amplifying a second RF signal;
a second temperature sensor output capable of effecting operation of the second broadband amplifier; and
wherein the second broadband amplifier operates when the first broadband amplifier is disabled.

Abstract
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. The module may also include a thermal protection system capable of effecting operation of the broadband power amplifier.
