Abstract: Certain aspects of the present disclosure generally relate to jamming detection for radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first counter configured to count a number of times that a power of a reception signal exceeds a first threshold. The apparatus also includes a second counter configured to count a number of measurements of the power of the reception signal. The apparatus further includes control logic having a first input coupled to an output of the first counter and having a second input coupled to an output of the second counter. The control logic is configured to determine an amount of jamming over a measurement window based on the number of times that the power of the reception signal exceeds the first threshold and on the number of measurements.

Abstract: An RF power detector controls an amplitude of a replica input signal so that a power of the replica input signal substantially equals a power of an input signal to the RF power detector. A signal generator generates the replica input signal responsive to a digital control word. A feedback circuit adjusts the digital control word responsive to a comparison of output signals from an analog power sensor.

Abstract: A switching mixer array is disclosed for the mixing of a digital LO signal with an analog input signal. Each switching mixer in the array is configured to assume either a first switching state or second switching state responsive to a respective bit of the digital LO signal.
