  • Publication number: 20130311127
    Abstract: Methods and apparatus are disclosed to simultaneously, wirelessly test semiconductor components formed on a semiconductor wafer. The semiconductor components transmit respective outcomes of a self-contained testing operation to wireless automatic test equipment via a common communication channel. Multiple receiving antennas observe the outcomes from multiple directions in three dimensional space. The wireless automatic test equipment determines whether one or more of the semiconductor components operate as expected and, optionally, may use properties of the three dimensional space to determine a location of one or more of the semiconductor components. The wireless testing equipment may additionally determine performance of the semiconductor components by detecting infrared energy emitted, transmitted, and/or reflected by the semiconductor wafer before, during, and/or after a self-contained testing operation.

  • Publication number: 20130287076
    Abstract: Communication processing paths include distortions, such as DC offset in the baseband analog path, local oscillator feed-through distortion, and nonlinearity of gm's and power amplifiers which are calibrated for, separately or in combination. The cascaded DC offset and nonlinear distortions are modeled separately or in combination using even-and-odd order polynomials. A loopback path from the output of one or more distortion causing devices passes through a measurement and calculation module. The calculation module calculates predistortion polynomial's coefficients which will be stored in a look-up table to be used by a baseband predistorter to calibrate the path. The look-up table is stored locally or remotely.
