Abstract: An RF detector configured to provide two outputs, one being a function of the true RMS power level of an RF input signal, and the other being a function of the instantaneous/peak power of the RF input signal, normalized to the average power level. The RF detector includes a variable gain detection subsystem including a single detector or detector array that provides a representation of the power level of the RF input signal. The detector or detector array is common to both the RMS power detection channel and the instantaneous/peak power detection channel of the RF detector. A method of RF detection includes providing representations of the RF input signal at different gain levels, selecting one or more of the representations, and averaging the selected signals. The gain levels of the selected representations is adjusted to provide information about the average power level of the RF input signal.

The input coupling circuit is operably coupled to receive a signal and to convert the signal into a first input and a rectifying input. The rectifying operational amplifier is operably coupled to receive the first input and the rectifying input and to produce therefrom a rectified output signal that represents a peak of the received signal. The charge pump converts the rectified output into a corresponding current, wherein the corresponding current represents power of the signal.

Abstract: An RF detector (15) is formed to compress the output voltage at two different rates depending on the value of the output voltage. Using two different rates of compression reduces saturation of the output voltage and reduces distortion. The RF detector (15) also provides temperature compensation in the output voltage to reduce output voltage variations due to temperature changes.

Abstract: An economical, wide range and accurate power measurement technique switches an RF detector between an applied RF IN to be measured and a COMPARISON RF IN, to thus develop a difference signal. The difference signal is filtered, amplified by a logarithmic amplifier, and then converted into a DC error signal by a synchronous detector operating in step with the switching of the RF detector. The DC error signal is applied to an integrator whose output is a loop control signal. Assuming a square law detector, the square of the loop control signal is linearly proportional to the applied RF IN once a servo loop is hulled by making COMPARISON RF IN equal to RF IN. The desired power measurement is performed by digitizing the loop control signal and performing the appropriate arithmetic operations thereon. The loop control signal is also applied to an analog multiplier, where it combines with an internal RF reference signal to produce, at the output of an attenuator following the multiplier, the COMPARISON RF SIGNAL. The entire loop servos to minimize the difference between the applied RF IN and the COMPARISON RF SIGNAL. When RF IN gets small an increase in attenuation allows the multiplier to continue to operate within an optimum dynamic range by reducing the COMPARISON RF SIGNAL to the same general level as RF IN.

Abstract: According to the present invention, a power amplifier with a plurality of power transistors has detection circuitry corresponding to each power transistor which detects the output power of the power transistors and allows this output power to be monitored and modified if desired. The detection circuitry generates a voltage output signal indicative of the rise and fall times achieved by the power transistor. The voltage output signal of the detection circuitry may be monitored by connecting the voltage output signal to a measuring device, such as an oscilloscope of built-in-test-equipment (BITE). Additionally, the voltage output signal of the detection circuitry may be modified by tuning input matching circuitry and/or output matching circuitry accordingly.
