    Abstract: An apparatus is provided. Transmission line cells are formed in a first region. A first metallization layer is formed over the transmission line cells within a portion of the first region. At least a portion of the first metallization layer is electrically coupled to the plurality of transmission line cells. A second metallization layer is formed over the first metallization layer with an interconnect portion, and overlay portion, and a first balun. The interconnect portion at least partially extends into the first region, and the overlay portion is within the first region. The first balun winding is electrically coupled to the overlay portion and partially extends into a second region. The first region partially surrounds the second region. A third metallization layer is formed over the second metallization layer having a second balun winding within the second region, where the second winding is generally coaxial with the first balun winding.

    Abstract: A method is provided. A first edge on a first gating signal is generated, and a local oscillator and a shared clocking circuit with the first edge on the first gating signal. A second edge on a second gating signal is generated following the first edge on the first gating signal, and a receiver circuit is activated with the second edge on the second gating signal, where the receiver circuit includes a mixer. A transmit pulse following the first edge on the first gating signal is generated with the transmit pulse having a third edge. A switch that short circuits outputs of the mixer is then released following the later of the third edge of the transmit pulse and a delay.

    Abstract: An apparatus is provided. In the apparatus, there is an antenna package and an integrated circuit (IC). A circuit trace assembly is secured to the IC. A coupler (with an antenna assembly and a high impedance surface (HIS)) is secured to the circuit trace assembly. An antenna assembly has a window region, a conductive region that substantially surrounds the window region, a circular patch antenna that is in communication with the IC, and an elliptical patch antenna that is located within the window region, that is extends over at least a portion of the circular patch antenna, and that is in communication with the circular patch antenna. The HIS substantially surrounds the antenna assembly.
