Abstract: A circuit includes first, second, third and fourth terminals, and first and second switches. The first switch switches a first signal from the first terminal to the second terminal or from the first terminal to the fourth terminal. The second switch switches a second signal from the third terminal to the second terminal or from the third terminal to the fourth terminal. The first switch comprises a first switching element with a first high-frequency switching transistor connected between the first terminal and the second terminal, and a second switching element with a second high-frequency switching transistor connected between the first terminal and the fourth terminal. The second switch comprises a third switching element with a third high-frequency transistor connected between the third terminal and the second terminal and comprises a fourth switching element with a fourth high-frequency switching transistor connected between the third terminal and the fourth terminal.

Abstract: One embodiment of the present invention relates to a transmitter within a single integrated chip substrate, which is capable of continuous beam steering of a transmitted radar beam as well as an option to change the physical position of the origin of the transmit radar beam. The transmitter has a signal generator that generates an RF signal. The RF signal is provided to a plurality of independent transmission chains, which contain independently operated vector modulators configured to introduce an individual phase adjustment to the high frequency input signal to generate separate RF output signals. A control unit is configured to selectively activate a subset of (e.g., two or more) the independent transmission chains. By activating the subset of independent transmission chains to generate RF output signals with separate phases, a beam steering functionality is enabled. Furthermore, the subset defines a changeable position of the transmitted radar beam.
