    The authors' aim is to demonstrate the possibility of building high quality factor (Q) integrated inductors in the conventional complementary metal-oxide semiconductor (CMOS) process without any additional processes of previous papers, such as thick gold layer or multilayer interconnection. The comparative analysis is extensively carried out to investigate the detailed variation of Q performance a... View full abstract»

    Most reported spatially combined or quasioptical amplifier arrays exhibit resonant narrowband performance (<10%) and have not addressed thermal management issues. We report a waveguide-based spatial combining scheme using broadband tapered-slot transitions, capable of realizing full waveguide band coverage (40% fractional bandwidth) with good thermal properties. An X-band prototype using eight ... View full abstract»

    Two class B GaAs field-effect transistor (FET) power amplifiers integrated with patch antennas have been designed and fabricated at 2.48 GHz. Both amplifiers are integrated with patch antennas, which serve as load and radiator. In one case, a standard patch design was used with random harmonic termination. In another case, a modified patch design was used, which allows the tuning of the second har... View full abstract»

    A technology has been developed that reduces the thermal resistance of monolithic microwave integrated circuits (MMICs). Novel processing techniques are used to fabricate thin-film capacitors and microstrip lines on the back side of the chip. The front side of the chip is metallized to serve as the ground-plane; the completed chip is assembled inverted so that the active devices are next to the he... View full abstract»

    The numerical dispersion relation (NDR) of the finite-difference time-domain method in general curvilinear coordinates (FDTD-GCC) is discussed for a two-dimensional (2-D) uniformly skewed mesh. The analysis shows that the average scheme, which is being used in the FDTD-GCC method, causes an additional numerical dispersion error. When this dispersion error is considered, the FDTD-GCC method holds t... View full abstract»

    Hybrid numerical techniques in time domain offer computationally efficient means of analysis of certain classes of microwave structures. One of the recently proposed techniques combines the finite-difference time-domain (FDTD) method with the eigenfunction expansion. This method has proven to be very efficient in the analysis of properties of complex planar transmission lines and waveguide discont... View full abstract»
