摘要： A radio receiver includes a first diversity antenna structure, a second diversity antenna structure, a first RF receiver section, a second RF receiver section, a combining module, and a baseband processing module. The first diversity antenna structure provides the received inbound RF signals from one of the plurality of first antennas based on a first antenna selection signal to produce first received inbound RF signals. The second diversity antenna structure provides the received inbound RF signals from one of the plurality of second antennas based on a second antenna selection signal to produce second received inbound RF signals. The first and second RF receiver sections are operably coupled to convert the first and second received inbound RF signals into first and second inbound baseband signals, respectively. The combining module combines the first and second inbound baseband signals to produce inbound baseband signals.

摘要： A radio frequency receiver front-end includes a low noise amplifier, a mixing stage, and a selectable channel filter. The low noise amplifier is operably coupled to amplify inbound RF signals to produce amplified inbound RF signals. The mixing stage is operably coupled to mix amplified inbound RF signals with a 1st local oscillation to produce a 1st intermediate frequency (IF) signal. The selectable channel filter is operably coupled to pass a 1st channel of the 1st IF signal when a channel select signal is in a 1st state and to pass a 2nd channel of the 1st IF signal when the channel select signal is in a 2nd state to produce a selected channel.

摘要： A method for reducing LO leakage in a radio frequency transmitter begins by producing analog outbound signals from digital outbound signals that represent transmit data. The processing continues by amplifying the analog outbound signals to produce amplified analog outbound signals. The process then continues by mixing the amplified analog outbound signals with a local oscillation to produce mixed signals having an LO leakage component. The processing then continues by attenuating the mixed signals having the LO leakage component to produce mixed signals having reduced LO leakage.

摘要： A method for determining isolation status of the RF repeater is provided. A modem in the repeater registers with a base transceiver station (BTS). Uplink output levels of a donor RF transceiver are calibrated and stored in the modem. The modem is synchronized to a BTS transmission received at the donor RF transceiver and the synchronization information is provided to a server RF transceiver of the repeater. Isolation detection and measurement can then be performed between donor transmit antenna and receive server antenna of the RF repeater and the automatic gain control parameter of donor RF transceiver and server RF transceiver are adjusted based upon the isolation detection and measurement value. The isolation and detection can be implemented in a co-processor coupled to the donor and server transceivers.
