Patent ID: 7830134

Claim:
A power meter and temperature sensor, comprising: a housing having an input connector for receiving an analog RF input signal a splitter for splitting said RF input signal into a low sense path and a high sense path; a first blocking capacitor and an attenuator, each disposed on said low sense path; a first log detector and temperature sensor succeeding said first blocking capacitor and said attenuator and having a thermal mass disposed on a common ground plane, and first log detector and temperature sensor having analog outputs; a second blocking capacitor and an amplifier disposed on said high sense path; a second log detector and temperature sensor succeeding said second block capacitor and said amplifier and having a thermal mass disposed on a common ground plane, said second log detector and temperature sensor having analog outputs, said second log detector and temperature sensor having the same dynamic range as said first log detector; an analog/digital converter for receiving the analog outputs from said first and second log detectors and temperature sensors; and a microcontroller for receiving the digital output from said analog-to-digital converter, said microcontroller including digital signal processing algorithms for applying temperature compensating power correction and digital integration to said digitized data and producing corrected power measurements.
