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.

Claims

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.

2. The method of claim 1, wherein the first broadband power amplifier and the temperature sensor are in a single die.

3. The method of claim 1, further comprising:

coupling the first RF signal through a first switch module to one of a plurality of transmission paths wherein each of said transmission paths are configured to transmit a different frequency band.

4. The module of claim 1, wherein the first broadband amplifier operates in the millimeter wave band.

5. The module of claim 1, wherein the first broadband power amplifier in the centimeter wave band.

6. The module of claim 1, wherein the first broadband power amplifier operates in the approximately 17 GHz to 100 GHz range.

7. The module of claim 1, wherein the first broadband power amplifier operates in the approximately 2.1 GHz to 7 GHz range.

8. The method of claim 1, further comprising:

effecting operation of the second broadband power amplifier through a second temperature sensor.
