ABSTRACT:
The specification relates to a radio frequency (RF) power detection circuit for multiple frequency bands. One embodiment of the present invention uses semiconductors as power detection sensors and as temperature compensation devices. Multiple power detection sensor current signals each develop a voltage signal across a common load resistor. Similarly, multiple temperature compensation sensor current signals each develop a voltage signal across a second common load resistor. A detector voltage and a temperature compensation voltage are then processed through common amplification circuitry, producing a signal proportional to sensed transmitted power.
