摘要：

We present two quadrature hybrid designs for operation at similar to 345 GHz. These hybrids were designed for sideband separating receivers currently in development for the wideband Submillimeter Array (wSMA). The first design uses a branch-line structure and simulated results show that the image rejection ratio, return loss and isolation are all above 20.6 dB from 280-360 GHz. The second hybrid is a novel design using silicon-mounted cross-guide probes. The simulated results show that the image rejection ratio, return loss and isolation are all above 28.0 dB from 330-360 GHz.
