Abstract: Apparatus and method example embodiments provide an improved common mode rejection ratio in high frequency transformer baluns. According to an example embodiment of the invention, an apparatus comprises a first winding of at least one turn forming a primary coil, having first and second differential leads oriented in a first direction, the primary coil formed in a first conductive layer over a substrate and the first differential lead of the primary coil being grounded; and a second winding of at least one turn forming a secondary coil, having a third and fourth differential leads oriented in a second direction offset by an angle of greater than zero degrees and less than 180 degrees from the first direction, the secondary coil formed in a second conductive layer separated by an insulating layer from the first conductive layer.

Abstract: Apparatus, method, and system example embodiments provide an improved integrated circuit RF front end to simultaneously transmit and receive signals for radar imaging. In an example embodiment, an apparatus comprises a transceiver coupled to a circularly polarized antenna assembly, capable of transmitting circularly polarized signals that are a component of a multi-signal radar beam; a power amplifier configured to amplify a transmit signal, coupled through isolation couplers to the circularly polarized antenna assembly; a phase shifting block circuit configured to perform phase shifting of a local oscillator signal, in response to the receipt of phase control signals, to perform phased-array beam steering of the multi-signal radar beam when the component circular signals are associated with signals transmitted from other transceivers receiving the phase control signals.
