    摘要: A microwave radio receiver includes a first down-converter, a second down-converter, and a combined receiver signal level (RSL) and interference detector. The first down-converter is configured to convert a RF signal into a first IF signal. The second down-converter is configured to convert the first IF signal into a second IF signal. The combined RSL and interference detector is configured to determine one or more RSLs and generate an interference indicator based on the first IF signal from the first down-converter and a control signal from the second down-converter.

    摘要: A transceiver used in a radio unit for wireless communication, comprises: a circuitry board including a transmitter and a receiver; a first connector on a first side of the circuitry board, wherein the first connector is configured to be connected to an interface card; a second connector on a second side of the circuitry board, wherein the second side is opposite the first side and the second connector is configured to be connected to a digital card via a flexible circuit; and a pair of transmit port and receive port located on the second side of the circuitry board, wherein the transmit port is coupled to the transmitter and the receive port coupled to the receiver, respectively. When the transceiver is part of a split-mount radio unit (SRU), the first connector is connected to the interface card and the second connector is not in use. When the transceiver is part of an all-outdoor radio unit (AOU), the second con vector is connected to the digital card and the first connector is not in use.

    摘要: A method for performing digital predistortion to a microwave radio transceiver in response to an increase/decrease of transmit power level is disclosed. If the new transmit power level is higher than the current transmit power level, a set of digital predistortion (DPD) coefficients is applied to the transceiver before the issuance of a transmit power level increase command to the transceiver. Otherwise, a transmit power level decrease command is issued to the transceiver before the application of the set of DPD coefficients to the transceiver. Determining the set of DPD coefficients for the transceiver involves two stages: (i) calibrating the transceiver at a room temperature under predefined conditions and generating a DPD lookup table including DPD coefficients at a plurality of predefined temperatures other than the room temperature and (ii) determining the set of DPD coefficients for a given set of operating conditions using entries in the DPD lookup table.
