RF polarizerHigh powerThis work presents the design of a novel X-band RF power splitter for high-power consumption. The RF power division ratio is adjusted by mechanically changing the position of a special RF short circuit piston, which is mounted on a step-motor to provide precise linear ...
from−1.25dB to 20 dB is realized in7, but the circuit uses a large number of different characteristic impedances. Planar magic-T-based voltage-controlled variable power divider with a maximum power division range of 14 dB is presented in8. However, the circuit has a phase difference of a...
(a) Schematic of the proposed power splitter, not including any vias, for which the geometry parameters are\(L_\mathrm{{tap}}=15\),\(L_1=3.8\),\(W_1=8\),\(L_t=1.68\),\(W_t=0.97\),\(D_t=2.3\),\(W_0=0.39\)and\(t_\mathrm{{sub}}=0.127\)all in the unit of mm. ...
Throughout the past decade, the complexity of nanophotonics circuitry increased exponentially, mixing non-linearity with dense nanoscale integration, advanced material manufacturing, and broad-band engineering functionalities [1–3]. Traditional intuition-driven design based on electromagnetic (EM) simulations...
Optical design software Zemax was used to choose the focal distance of aspherical lenses for maximization of the pump and signal coupling. The average output power of the laser was 4.0 W at maximum pump power of 8.1 W, showing an overall efficiency of ∼50%. For a pulse repetition rate ...
Accomplish array performance over a range of user-specified parameters such as power level and/or frequency. Perform various link-budget analyses of the RF feed network, including measurements such as cascaded gain, noise figure (NF), output power (P1dB), gain-t...
Nonetheless, this approach to design and optimization is not limited to these assumptions and can be generalized by adding more design groups for nanoantennae with variable dimensions. Additionally, the proposed DL models and the cyclical generation framework can be used to incorporate additional ...

Satellites are the most efficient way to achieve global scale quantum communication (Q.Com) because unavoidable losses restrict fiber based Q.Com to a few hundred kilometers. We demonstrate the feasibility of establishing a Q.Com uplink with a 3U CubeSat
