Patent JP-H01289301-A (JP)
Title: High frequency integrated circuit
Inventor: YOSHIMASU TOSHIHIKO
IPC: H01P5/02
Filed: 1988-05-17
Abstract: PURPOSE:To prevent the increase in the resistance loss as the characteristic impedance gets higher and the increase in the radiation loss when the characteristic impedance is decreased by constituting the circuit with a substrate, a dielectric substance having a different dielectric constant from that of the substrate and a transmission line made of a low resistivity metal or the like on the dielectric substance. CONSTITUTION:A substrate is made of GaAs and a dielectric substance 4 is made of SiO2. The dielectric constant of the SiO2 is nearly three and it is nearly 1/4 of that GaAs. While the characteristic impedance of a strip line formed on the GaAs substrate 1 is nearly 50OMEGA at 10GHz, the characteristic impedance of the strip line of the same width formed on the SiO2 is nearly 100OMEGA. Thus, the characteristic impedance is varied without varying the line width of the strip line. Then the increase in the resistance loss is suppressed when the characteristic impedance of the strip line is increased and the increase in the radiation loss is suppressed when the characteristic impedance is decreased.

CONSTITUTION:The disk substrate on which information pits are recorded is formed of the copolymerized resin of the methyl methacrylate (MMA) and styrene. This disk has the good stability at the time of molding, is economically low in material cost and has excellent transparency. However, this material contains the styrene system as the copolymer component and, therefore, the bending strength is weak in terms of physical strength with the disks having >=150mm diameter, but the material has the strength sufficient for practicable use with the disk substrates such as CD-single and CDs (12mm width) which are main applications and are inexpensively mass-produced. The optical disk which has the excellent moldability, decreases the double refractions, particularly decreases the camber of the disk formed with the reflecting film on one face and is extremely advantageous in cost is thereby obtd.
