- Ultra Linear Low-Loss Varactor Diode Configurations for Adaptive RF Systems
[作者:Huang, C; Buisman, K; Marchetti, M; Nanver, LK; Sarubbi, F; Popadic, M; Scholtes, TLM; Schellevis, H; Larson, LE; de Vreede, LCN,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:205-215 , 文章类型: Article,,卷期:2009年57-1]
- Two linear low-loss varactor configurations for tunable RF applications are compared. The wide tone-spacing varactor stack provides the best linearity for signals with relative large tone spacing like receiver jammer sit...
- A Dual Band Unequal Wilkinson Power Divider Without Reactive Components
[作者:Wu, YL; Liu, YN; Zhang, YX; Gao, JC; Zhou, H,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:216-222 , 文章类型: Article,,卷期:2009年57-1]
- This paper presents an unequal Wilkinson power divider operating at arbitrary dual band without reactive components (such as inductors and capacitors). To satisfy the unequal characteristic, a novel structure is proposed...
- A Novel Analytical Model as a Design Tool for Uni-Traveling-Carrier Traveling Wave Photo Detectors Approaching 1 THz
[作者:Madjar, A; Koka, N; Bloch, J; Yu, PKL; Stoehr, A; Jaeger, DS,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:223-230 , 文章类型: Article,,卷期:2009年57-1]
- The generation of sub-millimeter waves and terahertz signals is a difficult challenge, and a few approaches are being studied by several groups. We are investigating the approach of heterodyning two optical signals in a ...
