A compact E plane of 10 dB rectangular waveguide directional coupler with different lengths of branch waveguide operating at the center frequency of 340 GHz is presented. The coupler is fabricated using the micro-fabrication technology of deep reactive ion etching (DRIE). The S-parameter is measured by the two-port vector network analyzer and the result is consistent with that of simulation, which...
Future IP-based Airborne Networks, important components in net-centric military communications, are envisioned to consist of a persistent backbone core network and dynamic tactical edge networks. The backbone would consist of quasi-stable platforms equipped with multiple high-capacity directional wireless links. The tactical edge networks would consist of highly dynamic platforms such as fighter jets...
A new frequency compensation technique for low-power, area-efficient multistage amplifiers is introduced in this work. By utilizing active capacitors to realize the compensation network in a nested way, two inverting gain stages can be used as the second and third gain-stages. The proposed scheme reaches better bandwidth-to-power and slew-rate-to-power performances comparing to the ever published...
