<p>The present invention provides a method, system, and processor instructions for calibrating a modular wide-range microwave communication system. The system includes a first radio module (920) including a calibration memory and radio circuitry (e.g., RF transmit, RF receive, and IF circuitry), a test signal processing system (910) including a signal generator (911), measuring unit (912), memory (914), and a processor with instructions (913); and an oven or other controlled environment (930). The system is operable for controlling the signal generator to supply a series of test signal to the first radio module, for controlling the radio circuitry to set attenuation values, for controlling the measuring unit (912) to determine characteristics of the radio circuitry based on the series of test signals, and for determining calibration values based on the series of test signals, attenuation values, and the determined characteristics of the radio circuitry, whereby the calibration values are stored in the calibration memory of the radio module (920). A modular wide-range transceiver using precalibrated modular units, and its operation, is also discloses.</p> |
