Abstract: A state of a programmable mixer is set during a calibration phase to minimize local oscillator feedthrough. During a calibration phase, inputs to the programmable mixer are set to zero, or to a known state and the local oscillator is set to a calibration frequency. Then, one of a plurality of known calibration states of the programmable mixer is entered and the local oscillator feedthrough is measured. For each of a plurality of operating states an amplified output of the programmable mixer is measured. In one operation, the state of the programmable mixer in which the programmable mixer operates during a next operation phase is the state that produces minimal local oscillator feedthrough. In another operation, operation continues until a state is found that produces a local oscillation feedthrough that meets an operating criteria and that state is used during the next operation phase.

Abstract: An RSSI circuit provides a relatively inexpensive technique for accurately measuring received signal strength over a wide dynamic range. A received signal is processed by a rectifier circuit that generates a series of DC offsets of increasing magnitude. The DC offsets are imposed on a first polarity of the received signal to create a series of outputs that are the first polarity of the received signal with increasing DC offsets. Each of the outputs is coupled to one input of a weighted comparator with the other input of the comparator coupled to a second and opposite polarity of the received signal with no offset. The comparators determine when overlap occurs to indicate particular signal levels.
