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. A power amplifier module has a forward power (FP) sensor and a reflective power (RP) sensor. A Voltage Standing Wave Ratio (VSWR) Processing Control Circuit (VPCC) is configured to tune the matching antenna for optimal radio frequency operation and protect the power amplifier in conjunction with the power amplifier protection controller. 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.
