Abstract: A probe for sensing radio frequency power, utilizing two independently-driven radio frequency-sensitive diodes. The two diodes are driven through a common RF input, through a branch network which separates and feeds the probe RF power to each diode independently. The diodes are unequally padded from the RF input, to provide an extended sensitivity range for the probe. One diode, therefore, operates in a lower dBm range, while the other diode operates in a higher dBm range. Two separate outputs are provided from the probe to supply a common power meter which monitors the appropriate output for the present power level of the radio frequency input.
