- This paper presents results of fully packaged RF microelectromechanical (RF-MEM) switches including capacitive series, series-shunt, and single-pole-four-throw (SP4T) switch nodes. The RF-MEM capacitive switches are pack...
- A triple-tuned ultra-wideband VCO
[作者:Tsuru, M; Kawakami, K; Tajima, K; Miyamoto, K; Nakane, M; Itoh, K; Miyazaki, M; Isota, Y,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:346-354 , 文章类型: Article,,卷期:2008年56-2]
- We have already proposed a triple-tuned voltage-controlled oscillator (VCO) for achieving an ultra-wideband characteristic. The triple-tuned VCO consists of an active device and three tuned circuits. The fabricated VCO h...
- FDTD calculations of specific absorption rate in fetus caused by electromagnetic waves from mobile radio terminal using pregnant woman model
[作者:Togashi, T; Nagaoka, T; Kikuchi, S; Saito, K; Watanabe, S; Takahashi, M; Ito, K,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:554-559 , 文章类型: Article,,卷期:2008年56-2]
- Since the diversification of the electromagnetic (EM) environment is spreading, it is essential to estimate the EM energy absorption rate [specific absorption rate (SAR)] of a pregnant woman's body and her fetus under va...
