    摘要： At very high frequencies, generally above 100 GHz, the performance of traditional radio frequency (RF) circuitry begins to significantly limit performance. An example is the hybrid coupler, which can have a relatively narrow 90° bandwidth in these frequency ranges. Here, however, a branch-line hybrid coupler (which has been integrated into a quadrature downconversion mixer) has been modified. Namely, an adjustable impedance network has been coupled to isolation port (which has traditionally been terminated) to substantially increase the tuning range and expand the bandwidth of the quadrature mixer within these very high frequency ranges.

    摘要： Blixers, which are a relatively recent development, have not be studied as extensively as many older circuit designs. Here, a blixer is provided that improves linearity and reduces noise over other conventional blixer designs. To accomplish this, the blixer provided here uses a differential amplifier and/or a dummy path within its mixing circuit to perform noise reduction (and improve linearity).

    摘要： An antenna is provided. This antenna is contained within a package that is secured to an IC (which allows radiation to propagated away for a printed circuit board so as to reduce interference), and this antenna includes two loop antennas that are shorted to ground and that “overlap” and includes a “via wall.” With this configuration, circular polarization can be achieved by varying the relative phases of the input signals, and the “via wall” improves efficiency by reducing surface waves.

    摘要： A loop antenna is provided. The apparatus comprises a substrate, a first metallization layer, and a second metallization layer. The substrate has first and second feed terminals and a ground terminal. The first metallization layer is disposed over the substrate and includes a first window conductive region, a first conductive region, a second conductive region, and a third conductive region. The first conductive region is disposed over and is in electrical contact with the first feed terminal; it is also is substantially circular and located within the first window region. The second conductive region is disposed over and is in electrical contact with the second feed terminal; it is also substantially circular and is located within the first window region. The a third conductive region is disposed over and is in electrical contact with the ground terminal, and the third conductive region substantially surrounds the first window region. The second metallization layer is disposed over and is in electrical contact with the first, second, and third conductive regions of the first metallization layer, and the second metallization layer includes a second window region that is at least partially aligned with the first window region.

    摘要： An apparatus is provided. A plurality of transceiver antennas are arranged to form a phased array, where each antenna include a differential transmit antenna and a differential receive antenna arranged in a first pattern. A plurality of transceivers are arranged in a second pattern that is substantially symmetrical, and each transceiver is associated with at least one of the transceiver antennas and includes a feed network. Each feed network has a power amplifier (PA), a first matching network that is coupled between the PA and its associated transmit antenna so as to translate the phase of each differential transmit signal, a low noise amplifier (LNA), and a second matching network that is coupled between the LNA and its associated receive antenna so as to translate the phase of each differential receive signal.
