| Abstract(in English) | 3-D MMIC technology is expected to extremely miniaturize circuit components as well as to increase the integration level of multi-functional MMICs. However, for application to practical products, it is still necessary to make efforts and inventions that suppress (or remove) the influences of the transmission line losses and the limited number of dielectric layers. In this paper, some practical methods for improving: LNA 's noise figure; MIX 90° coupler's insertion loss and balance; and 2φ modulator's bandwidth and operation speed, are discussed over the fabricated devices. The dielectric layer structure we use consists of five polyimide layers over GaAs substrate. The 5-layer polyimide structure is designated to be humidity proof and the 90° coupler effectively uses this layer structure. |
