    • A planar Magic-T that incorporates complementary microstrip-slotline tee junction and microstrip-slotline transition area to produce a compact broadband out-of-phase combining structure with minimum loss due to slotline radiation. The Magic-T structure layout is symmetric which causes the structure to be less dependent on the transmission line phase variation. The Magic-T produces broadband in-phase and out-of-phase power combiner/divider responses, has low in-band insertion loss, and small in-band phase and amplitude imbalance. A multi-section impedance transformation network is used to increase the operating bandwidth and minimize the parasitic coupling around the microstrip-slotline tee junction. As a result, the improved magic-T has greater bandwidth and lower phase imbalance at the sum and difference ports than the earlier magic-T designs.
    • 一个平面的Magic-T,其包含互补的微带槽线三通和微带槽线过渡区域,以产生紧凑的宽带异相组合结构,由于槽线辐射而具有最小的损耗。 Magic-T结构布局是对称的,这导致结构较少依赖于传输线相位变化。 Magic-T产生宽带同相和异相功率组合器/分频器响应,具有低带内插入损耗,以及小带内相位和幅度不平衡。 使用多段阻抗变换网络来增加工作带宽并最小化微带槽线三通路周围的寄生耦合。 因此,与之前的魔术T设计相比,改进的魔术T具有更大的带宽和总和和差异端口的较低相位不平衡。

    • A signal conditioning module provides a polarimeter capability in a photometric system. The module may include multiple variable delay polarization modulators. Each modulator may include an input port, and a first arm formed to include a first reflector and first rooftop mirror arranged in opposed relationship. The first reflector may direct an input radiation signal to the first rooftop mirror. Each modulator also may include an output port and a second arm formed to include a second reflector and second rooftop mirror arranged in opposed relationship. The second reflector can guide a signal from the second rooftop mirror towards the output port to provide an output radiation signal. A beamsplitting grid may be placed between the first reflector and the first rooftop mirror, and also between the second reflector and the second rooftop mirror. A translation apparatus can provide adjustment relative to optical path length vis-a-vis the first arm, the second arm and the grid.
