| Abstract(in English) | This paper describes a development of reducing die size of a microwave monolithic integrated circuit (MMIC) power amplifier (PA). This is realized as follows : First, process improvement, where GaAs substrate and SiN film of MIM capacitors are thinned half, respectively. Second, reconsideration of pattern layout rules, where minimum line width and spacing between transmission lines are reduced to process constraints using electromagnetic simulation. The die size of a 3-GHz 1-W MMIC PA newly developed with these technologies is 1.9 mm x 2.1 mm, which is reduced to about 40 % of that of an existing PA. This MMIC PA shows good small signal performances of a linear gain of 33 dB, input and output return losses of more than 10 dB over a wide frequency range of 3.4 to 3.8 GHz. It also shows an output power of 30.5 dBm with a power added efficiency of 29 % at 1-dB gain compression and an output power of 32.0 dB n with a power added efficiency of more than 41 % at 3-dB gain compression, respectively. These results confirm the validity of this development. |
