具有有源器件调谐的反射型相位偏移器
摘要：
一种相位偏移器包括第一RF端子和第二RF端子，参考电势端子；连接至第一RF端子和第二RF端子以及参考电势端子的集总元件LC网络，以及连接至集总元件LC网络和参考电势端子的第一有源半导体器件和第二有源半导体器件。第一有源半导体器件和第二有源半导体器件中的每个有源半导体器件包括控制端子以及第一输出端子和第二输出端子。集总元件LC网络呈现跨第一RF端子和第二RF端子的电抗，偏移在第一RF端子和第二RF端子之间RF信号的相位。第一有源半导体器件和第二有源半导体器件被配置用于通过控制跨第一RF端子和第二RF端子的电抗调谐RF信号的相位偏移。
摘要（英）：

A phase shifter includes first and second RF terminals, a reference potential terminal; a lumped element LC network connected to the first and second RF terminals and the reference potential terminal, and first and second active semiconductor devices connected to the lumped element LC network and to the reference potential terminal. Each of the first and second active semiconductor devices include a control terminal and first and second output terminals. The lumped element LC network presents a reactance across the first and second RF terminals that shifts the phase of an RF signal as between the first and second RF terminals. The first and second active semiconductor devices are configured to tune the phase shift of the RF signal by controlling the reactance across the first and second RF terminals.
