“…This LNA MMIC consists of 3-stages InGaP/InGaAs pseudomorphic HEMTs (p-HEMTs), which is fabricated on a semi-insulated GaAs substrate with 0.15-[pm-long T-shaped gate electrode [2], [3]. A schematic cross section of the HEMT is shown in Figure 1.…”

“…According to the finite conductivity of the metal (2. 5 10 S.m for gold metallization) and to the (0.0003) of the GaAs substrate, very high insertion losses are expected when designing such narrow-band filters. These insertion losses can be predicted roughly from (4).…”

This paper deals with the design of passive coplanar devices in the -frequency band. As long as coplanar transmission lines are correctly dimensioned, analytical models based on quasi-TEM approximation can be used. Such models are associated with a correct definition of the reference planes at the junctions and employed for junction discontinuities, T-and cross-junctions. In order to validate these assertions, simulated and experimental data on classical quarter-wavelength shunt-stub filters are first presented. Then the design of traditional coupled-line filters is examined. The problems in terms of insertion loss associated with these kinds of narrow-band applications are discussed here. Minimization of insertion losses requires increasing the width of the strips. Consequently, the design becomes complex and modeling using transmission-line models less accurate. Nevertheless, as an optimization procedure is needed to tune the filter theoretically, such a very fast design method is necessary. Simulated and experimental results in the range 500 MHz to 110 GHz are compared throughout the paper.

“…We must therefore find a compromise between roughness and mechanical strength. In the millimetre and sub-millimetre frequency range coplanar waveguides are more commonly used in the design of circuits (Argarwal et al, 1998), (Haydl et al, 1999), (Hirose et al, 1998), (Papapolymerou et al, 1999). Many studies have, indeed, shown that coplanar waveguides can be considered as a good alternative to microstrip lines in this frequency range (Houdard, 1976), (Hirota & Ogawa, 1987), (Ogawa & Minagawa, 1987), (Brauchler et al, 1996), (Kulke & Wolff, 1996), (Herrick et al, 1998).…”
