    摘要: The present invention provides a system for wide-range microwave communications over wireline networks. In an exemplary embodiment, a wide-range transceiver is made having pre-calibrated modular units including an IF radio processing card, an RF transmitter module, and an RF receiver module. Calibration factors are loaded into a memory (e.g., EEPROM) in each module during production. Certain additional calibration factors may also be loaded upon installation, such as a one time calibration for the type and length of cable connecting the RF unit to a remote SPU (signal processing unit). A processor in the RF unit is responsive to control signaling indicating a desired transmitter or receiver configuration (e.g., a particular frequency, bandwidth and modulation), to attenuate the signal in the transmitter/receiver path based on the predetermined calibration factors from the applicable modules. A method for calibrating the modules is also disclosed.

    摘要: Each radio of a plurality of radios includes a plurality of variable gain stages connected in series. The radio further includes at least one power detector connected to the variable gain stages, a temperature sensor, and a processor for controlling the variable gain stages in-service based upon the at least one power detector, the temperature sensor, and stored frequency and power compensation values. A method for calibrating each radio includes generating frequency compensation values for at least one first variable gain stage by supplying a first calibration signal swept in frequency while maintaining the radio at a constant temperature. The method further includes generating power compensation values for at least one second variable gain stage by supplying a second calibration signal swept in power level and while maintaining the radio receiver at a constant temperature. The frequency and power compensation values generated at the constant temperature are stored for use by the processor during in-service temperature variations.

The system is operable for controlling the signal generator to supply a series of test signals to the first radio module, for controlling the radio circuitry to set attenuation values, for controlling the measuring unit to determine characteristics (e.g., output power) 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. A modular wide-range transceiver using pre-calibrated modular units, and its operation, is also disclosed.
