摘要： A radio use case is determined for concurrently operating radios of a multi-radio device and/or transmitter and receiver of a FDD radio. A local memory is accessed with the determined use case to find a high and/or a low frequency cutoff for the concurrent operation radio or transmitter/receiver. Control signals are applied to impose the high and/or the low frequency cutoff to a pair of frequency adjustable diplexers that are in series with one another in one of a transmit branch or a receive branch of a duplexer circuit that is disposed between the radio and an antenna. Then, a receive signal is passed through the antenna and the receive branch of the duplexer circuit to the radio or receiver of the FDD radio, or a transmit signal is passed from the respective radio or transmitter of the FDD radio through the transmit branch of the duplexer circuit to the antenna.

摘要： A mobile station is constructed to include a transceiver comprising a transmitter circuit having a transmit RF filter that passes a transmit band of frequencies that is partitioned into transmit frequency channels and a receiver circuit having a receiver RF filter that passes a receive band of frequencies that is partitioned into receiver frequency channels. Also included is an antenna coupled through a duplexer to an output of the transmitter circuit and to an input of the receiver circuit. The mobile station further includes circuitry, responsive to a currently selected RF channel, for compensating for a non-ideal operation of the RF filters and the duplexer over a full bandwidth range of the transmit and receive frequencies. The compensating circuitry compensates for RF filter operation in a transmit RF channel that is nearest to the band of receive RF frequencies and/or compensates for RF filter operation in a receive RF channel that is nearest to the band of transmit RF frequencies. The compensation circuitry can be implemented using a digital signal processor (DSP) device or a finite impulse response (FIR) device. In the preferred embodiment the transmit and the receive ranges of frequencies are each about 60 MHz and are each partitioned into 12 frequency channels, and a highest frequency channel in the transmit range of frequencies and a lowest frequency channel in the receive range of frequencies are separated by about 20 MHz.

摘要： There are first and second antennas proximally disposed and configured to resonate within respective first and second frequency bands, which may overlap. An impedance stabilization circuitry is coupled to ground. There is a selective coupler (for example, diplexer, directional coupler, switch) interfacing the second antenna selectively with the impedance stabilization circuitry and with radio circuitry. The selective coupler comprises a first port coupled to the second antenna, a second port coupled to the impedance stabilization circuitry, and a third port configured to couple with radio circuitry that is configured to operate in the second frequency band. The selective coupler provides a predetermined impedance to signals within the first frequency band and a low insertion loss to signals within the second frequency band, thus providing a stable impedance for the first antenna's view of the second antenna.

摘要： A method and device for achieving space diversity reception in a system that has a first antenna and a second antenna disposed apart from each other over a quarter wavelength of the operating frequency, wherein the first antenna is optimally tuned to a first frequency for receiving signals in an operating mode. In its first function, the second antenna is optimally tuned to a second frequency for transmitting signals in the same mode or for receiving signals in a different mode. In its second function, the second antenna can be tuned to the first frequency so that it also receives signals in the first frequency in the same mode as the first antenna. The signals in the first frequency received by the second antenna are combined with the signals received by the first antenna.
