Embodiment Construction

[0021] figure 1 Transceiver means for receiving and transmitting signals according to different mobile telephony standards are shown. The transceiver means is implemented as an integrated circuit in the semiconductor 1A. The semiconductor has a number of connection contacts on its surface for input or output of high-frequency signals. The input high-frequency signal is amplified and further processed, wherein the term signal processing is generally to be understood as frequency conversion to an intermediate frequency, digitization and / or subsequent demodulation. To process signals according to different mobile telephone standards, different circuit components are implemented in multiples. The circuit part is thus optimized for the respective application involving the particular mobile phone standard.

[0022] Thus, for example, with the mobile telephone standard UMTS / WCDMA, the data content is transmitted in amplitude and phase. It is therefore expedient to amplify the rec...

Abstract

A transceiver arrangement includes a first receive path with a first connection and a first receive amplifier, and a second receive path with a second connection, a second receive amplifier, and a frequency conversion device. A controllable coupling device is configured to couple an output of the first receive amplifier to an input of the frequency conversion device on the second signal path. Furthermore, the transceiver arrangement includes a control circuit configured to deliver a control signal to the coupling device for combining signals delivered by the first and second receive amplifierin the correct phase based on a signal supplied by the receive paths. This achieves receive diversity wherein, on the one hand, additional external components are no longer necessary.

Description

technical field [0001] The invention relates to a transceiving device and method for processing signals, especially suitable for mobile phones. Background technique [0002] Recently the number and flexibility of application approaches for communication devices, especially mobile communication devices, has increased dramatically. Modern communication devices can thus simultaneously receive and transmit signals according to different mobile communication standards. The so-called 3G communication device can receive signals according to the mobile telephony standard WCDMA / UMTS as well as according to the mobile telephony standard GSM or Edge, for example. This makes it possible to find users in regions with different reach or different so-called network coverage. [0003] The high degree of flexibility in the use of mobile communication standards allows for different applications on the one hand and high data transfer rates on the other hand, taking into account the changing ...
