摘要： The invention relates to a multi-modelmulti-band wireless transceiver. The multi-mode/multi-band wireless transceiver includes a tunable duplexer including transmission and reception channel filters of which transmission and reception channel filtering frequencies respectively are controlled by an external element; and a control portion for controlling the transmission and reception channel filtering frequencies to correspond to transmission and reception channels of a current service band. Thus, a use of a RF SAW filter is unnecessary, while it is possible to support the multi-mode/multi-band using a tunable duplexer. Therefore, the number of parts and volume of the transceiver can be reduced, and it is possible to weaken a specification of an RF system.

摘要： A multi-mode wireless device having a transceiver including a multi-mode transmitter and a multi-mode receiver. The transmitter can include a multi-mode transmit baseband portion configured to support all of the transmit modes. Similarly, the receiver can include a multi-mode baseband portion that is configured to support all of the receive modes. The transmitter can also include a frequency conversion stage that can convert the modes, can selectively amplify the transmit signals. The receiver can include multiple low noise amplifiers (LNAs) in parallel, each configured to selectively amplify the received signals of one or more of the operating modes. The output of the LNAs can be coupled to a frequency conversion stage that downconverts the received signals and provides them to the baseband portion.

摘要： Radio communication apparatus includes a baseband processor (72) for modulating data to be transmitted into an IF signal and for demodulating an IF signal derived from a received high frequency signal. A front end section (73) receives the IF signal from the baseband processor (72) and converts that IF signal into a high frequency signal for transmission. The front end section (73) also receives a high frequency signal from a remote location, and converts the received high frequency signal into an IF signal that is supplied to the baseband processor (72) for demodulation and data recovery. The front end section (73) is operable in a plurality of frequency bands and is tunable to a frequency within a selected one of the frequency bands for use as a radio frequency channel. Consequently, the number of simultaneously assigned channels in the same area can be markedly increased and the possibility of interrupting a communication link is significantly reduced.

摘要： A radio transceiver (400, 450) is intended for transmission and reception of radio signals in two frequency bands, and it comprises a first signal input (101) for receiving radio signals in the first frequency band, and a second signal input (102) for receiving radio signals in the second frequency band. In addition, it comprises
a first mixer connected to the first signal input (101) for mixing the radio signals (DCS RX) in the first frequency band onto a predetermined first intermediate frequency (IF1);
a second mixer (404) for mixing the first intermediate frequency (IF1) onto a predetermined second intermediate frequency (IF2); and
a third mixer (402, 461) connected to the second signal input (102) for mixing the radio signals (GSM RX) in the second frequency band onto a predetermined frequency (IF2), which is substantially the same as the second intermediate frequency.摘要翻译： 无线电收发器（400,450）旨在用于在两个频带中发送和接收无线电信号，并且其包括用于接收第一频带中的无线电信号的第一信号输入（101）和第二信号输入（102） 用于在第二频带中接收无线电信号。 另外，它包括连接到第一信号输入（101）的第一混频器，用于将第一频带中的无线信号（DCS RX）混合到预定的第一中频（IF1）上; 用于将第一中频（IF1）混合到预定的第二中频（IF2）上的第二混频器（404）; 以及连接到第二信号输入端（102）的第三混频器（402,461），用于将第二频带中的无线电信号（GSM RX）混合到与第二中频基本相同的预定频率（IF2）上 。
