Abstract

Examples provide an adaptation circuit and apparatus, method and computer programs for adapting, fabricating and operating, a radio transceiver, a mobile transceiver, a base station transceiver and storage for computer programs or instructions. The adaptation circuit (10) is configured to adapt a local oscillator signal in a radio transceiver (30). The radio transceiver (30) comprises a transmission branch (14) and a reception branch (16), which are subject to cross-talk. The reception branch (16) comprises a local oscillator (18) configured to generate the local oscillator signal. The adaptation circuit (10) comprises a control module (12) configured to determine crosstalk level information between the transmission branch (14) and the reception branch (16), and to adapt the local oscillator signal based on the crosstalk level information.
