- Design of a Highly Efficient 2-4-GHz Octave Bandwidth GaN-HEMT Power Amplifier
[作者:Saad, P; Fager, C; Cao, HY; Zirath, H; Andersson, K,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1677-1685 , 文章类型: Article,,卷期:2010年58-7]
- In this paper, the design, implementation, and experimental results of a high-efficiency wideband GaN-HEMT power amplifier are presented. A method based on source-pull/load-pull simulation has been used to find optimum s...
- An Integrated Divide-by-Two Direct Injection-Locking Frequency Divider for Bands S Through K-u
[作者:Dal Toso, S; Bevilacqua, A; Tiebout, M; Da Dalt, N; Gerosa, A; Neviani, A,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1686-1695 , 文章类型: Article,,卷期:2010年58-7]
- In this work, direct injection locking is applied to a ring oscillator topology to design a wideband divide-by-two frequency divider circuit with a locking range covering bands S through K-u, namely input frequencies fro...
- An Octa-Push Oscillator at V-Band
[作者:Kawasaki, K; Tanaka, T; Aikawa, M,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1696-1702 , 文章类型: Article,,卷期:2010年58-7]
- In this paper, an octa-push oscillator is first presented. An N-push oscillator principle is effectively adopted. The proposed oscillator consists of eight sub-circuits, a microstrip ring resonator, and an output circuit...
- Harmonic Generation Using Nonlinear LC Lattices
[作者:Lilis, GN; Park, J; Lee, W; Li, GS; Bhat, HS; Afshari, E,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1713-1723 , 文章类型: Article,,卷期:2010年58-7]
- Nonlinear LC lattices have shown promise for high-power high-frequency signal generation. Here we offer the first detailed study of the frequency response of these lattices, as well as a method designed to find input exc...
- Electromagnetic-Bandgap Waveguide for the Millimeter Range
[作者:Ederra, I; Khromova, I; Gonzalo, R; Delhote, N; Baillargeat, D; Murk, A; Alderman, BEJ; de Maagt, P,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1734-1741 , 文章类型: Article,,卷期:2010年58-7]
- This paper presents the design, manufacturing, and characterization of a waveguide based on electromagnetic-bandgap (EBG) technology working in W-band. A modified silicon EBG woodpile structure was used in order to impro...
- Identifying RF Identification Cards From Measurements of Resonance and Carrier Harmonics
[作者:Romero, HP; Remley, KA; Williams, DF; Wang, CM; Brown, TX,期刊:IEEE Transactions on Microwave Theory and Techniques, 页码:1758-1765 , 文章类型: Article,,卷期:2010年58-7]
- We show that careful measurements of the unloaded resonance frequency and quality factor of RF identification proximity cards allow identification of different card models and, for the set of cards we studied, identifica...
