“…The chip sizes are 1mm × 2.45mm for the conventional DA and 1.15mm × 2.65mm for the proposed one. Because the gate or drain line lengths of the novel structure are shorter than the conventional one according to (4), the overall chip size of novel structure is slightly larger than that of conventional DA in spite of two baluns and two six-cell DAs.

“…If the gate and drain line characteristic impedance is less than 50Ω, limitations mentioned above can be overcome. Assuming Z 0 to be 25Ω, the line length between FETs can be reduced to four times according to (4). Also the bandwidth of DA can be two times wider than that of conventional 50Ω-matched DA, maintaining the FET gate width.…”

-A novel balanced distributed amplifier (DA) was proposed using novel impedance transforming MEMS baluns. The impedance transforming MEMS balun is matched to 50Ω at one input port and 25Ω at two output ports. It is based on the electric field mode-change method, thus it is strongly independent of frequency and very compact. The novel balanced DA consists of two 25Ω-matched DAs and these are combined by 50Ω-to-25Ω baluns. Theoretically, it has two times wider bandwidth and power capability than the conventional DA. So as to verify the proposed concept, we designed and fabricated a conventional DA and the proposed one using 0.15-µm GaAs pHEMT technology.

In this work, a novel circuit topology is introduced for the implementation of multiplexers and demultiplexers, called ''active distributed (de)multiplexers.'' The desired characteristics of active distributed (de)multiplexers as being wideband, planar and active are realized by the proposed microwave circuit. A numerical methodology is presented for its design. An active distributed detriplexer is designed, simulated, fabricated, and measured by the proposed numerical procedure. Computer simulation and measurement results show the effectiveness and suitability of the proposed topology as a detriplexer.

“…The operation principle of the proposed de-triplexer is similar to distributed amplifiers, except that it has three gate transmission lines instead of one gate transmission line. The operation principles of distributed amplifiers are described in many articles and we do not repeat their details [8][9][10]. In the figures, the Eplane is the XZ plane and the H-plane is the YZ plane.…”

In this article, a novel approach is introduced for the design of wideband antennas in a specified frequency bandwidth (BW). In the proposed approach, the frequency BW is divided into some sub-bands. Then, the narrowband antennas are designed for the consecutive frequency sub-bands, and the antennas are connected together by a proposed active circuit, so that their frequency BWs combined. The proposed active circuit may be used to connect as many as antenna needed for the design. An active microstrip antenna is designed for the frequency BW of 4-10 GHz with a gain better than 5 dB by the proposed method. Fabrication and measurement results show the effectiveness of the proposed methodology. V C 2010 Wiley Periodicals, Inc. Int J RF and Microwave CAE 20: 408-415, 2010.
