Abstract: A coupling element is disclosed, comprising four coils that are arranged such that each one of the coils extends both in a first layer and a second layer. The first layer and the second layer are stacked with respect to each other and separated by an intermediate dielectric layer. The layout of each layer is configured to provide a transformer coupling between a first one and a third one of the coils, and between a second one and a fourth one of the coils. Further, the first coil and the second coil, and the third coil and the fourth coil, respectively, are routed so as to allow a differential signaling. A semiconductor device and a differential hybrid coupler comprising the coupling element are also disclosed.

Abstract: Example embodiments relate to transmitter-receiver leakage suppression in integrated radar systems. One embodiment includes a front-end for a radar system. The front-end includes a transmit path that includes a power amplifier and a transmit antenna. The transmit path is configured to transmit a transmit signal. The front-end also includes a receive path that includes a receive antenna and a low-noise amplifier. The receive path is configured to receive at least a leakage from the transmit path. The receive path is configured to generate an amplified signal of the leakage. Further, the front-end also includes a reference path. In addition, the front-end includes a compensation unit in the reference path. The compensation unit is configured to generate compensation for a leakage path between the transmit path and the receive path. The compensation unit is configured to apply the generated compensation to the reference signal to generate a compensated reference signal.

Abstract: Front-end systems for a transmitter included in a radio device are disclosed. An example front-end system may comprise a voltage-to-power mixer. The voltage-to-power mixer may be configured to up-convert a baseband signal to a high-frequency signal by multiplying the baseband signal with a local oscillator signal. Additionally, the voltage-to-power mixer may include a voltage feedback circuit. The example front-end system may further comprise a two-stage power amplifier. The two-stage power amplifier may be configured to amplify the high-frequency signal.
