Integrated circuit for use as motor vehicle-radar circuit, has circuit sections with respective couplers that are connected with input terminal, and mixers connected with respective couplers, where couplers and mixers are integrated on chip

摘要

The circuit (100) has a differential input terminal (120), and circuit sections (100a, 100b) comprising corresponding couplers (140a, 140b), which are connected with the input terminal. A mixer (110a) and an antenna connection (150a) are connected with the coupler (140a). Another mixer (110b) and another antenna connection (150b) are connected with the coupler (140b), where the couplers and mixers are integrated on a chip. An independent claim is also included for a method for transmitting and receiving high frequency signals.
