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:
An antenna RSSI meter includes a microcontroller unit for digitizing an antenna receiver voltage signal, converting the digitized antenna receiver voltage signal into a receiver signal level in accordance with a predefined antenna specification, and converting the receiver signal level into the antenna tuning signal in accordance with the predefined antenna specification. The antenna RSSI meter includes an input communication port for receiving the antenna receiver voltage signal from an antenna and providing the antenna receiver voltage signal to the microcontroller unit, The antenna RSSI meter also includes an output communication port for receiving the antenna tuning signal from the microcontroller unit and providing the antenna tuning signal to an antenna auto-aligning mechanism for adjusting position and orientation of the antenna.
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 connector is connected to the digital card and the first connector is not in use.
