Abstract
The present invention provides a true average wide dynamic range (TA-WDR) power sensor that can be used to make accurate power measurements from −70 dBm to +20 dBm or more (wide dynamic range), regardless of the format of the signal (true average). In one preferred embodiment, the present invention provides a true average wide dynamic range power sensor comprising an input for receiving RF signals having wide dynamic power ranges, a first RF path including a low power diode sensor for measuring RF signals having low power ranges, a second RF path including an attenuator high power sensor for measuring RF signals having high power ranges, and a switch for isolating the first RF path when the high power RF signals exceeds the square law region of the diode sensor.
