Transceiver arrangement and method for processing a signal
First Claim
1. A transceiver arrangement, comprising:
- a first receive path comprising a first connection and a first receive amplifier;
a second receive path comprising a second connection, a second receive amplifier, and a frequency conversion device;
a controllable coupling device configured to couple an output of the first receive amplifier to an input of the frequency conversion device on the second signal path; and
a control circuit configured to provide a control signal to the coupling device for selectively combining signals delivered by the first and second receive amplifiers in the correct phase based on a parameter which is derived from a signal present at the first connection or second connection, or both,wherein the signals are selectively combined prior to the frequency conversion device; and
wherein the parameter comprises a signal to noise ratio or a mobile radio standard.

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 amplifier in 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 and, on the other hand, adequate signal quality is ensured even with a simultaneous transmit process of the transceiver arrangement.
