电子、通信与自动控制技术

• 可调谐

  Also then the characteristic of phase noise, stability and tunability are investigated.

  然后对振荡器的相位噪声特性、频率稳定性以及可调谐特性也进行了研究。

• 调谐率

  It is found that the tunability of films with multilayer structure increases, and the dissipation factor did not change evidently.

  与外延多层薄膜不同，本文发现多层结构在显著提高薄膜的介电常数和调谐率的同时，介电损耗没有明显增加。

• 可调性

  According to the simulation results, a lot of aspects of system performance, such as the tunability of core frequency, the bandwidth of signal treatments, have been improved.

  仿真结果表明，中心频率的可调性、信号处理的带宽等多方面性能都有改进。

机械工程

• 可调性

  With the deposition power increased, the crystallization property of the PST thin fihns increases, and the dielectric tunability of the PST thin fihns increases.

  增大溅射功率,可以增强PST薄膜结晶性能,提高薄膜介电可调性。

化学

• 可调率

  Ferroelectric material employed in ferroelectric phase shifter must have these basic requirements: moderate dielectric constantεr , low dielectric loses (tanδ) and high dielectric constant tunability.

  用于制作铁电移相器的铁电材料须具备以下性能:适中的介电常数、低的介电损耗和高的可调率。
