摘要:
In a radio telephone equipment which includes a portable radiotelephone (100) and a booster (400), an output from the portable radiotelephone (100) whose output level is set according to a level control signal transmitted from a base station is amplified with a preset amplification factor by an automatic gain control circuit (22) provided in the booster (400). As a result, since the amplification factor of the amplifier in the booster and the portable radiotelephone are independently controlled, the booster can be connected to even a portable radiotelephone which is designed without considering that it will be connected to the booster.

The GaN-based semiconductor element 20 of the present invention comprises the buffer layer 2 formed on the sapphire (0001) substrate 1, the channel layer 3 comprised of the undoped GaN layer, and the electron supply layer 4 comprised of the undoped AlGaN layer. The buffer layer 2 is comprised of the n-GaN layer having n-type conductivity. The configuration is adopted as the structure to be able to control the electric potential of the buffer layer 2, wherein the source electrode 6 is implanted into the epitaxial layer (the channel layer 3 and the electron supply layer 4) to be formed on the buffer layer 2, and it is extended to the depth reaching the buffer layer 2 for ohmic contacting to the buffer layer 2. It is able to fix the electric potential of the buffer layer 2 comprised of the n-GaN layer for being equal to that of the source electrode 6 because the source electrode 6 is ohmic contacted to the buffer layer 2.
摘要:
A method of producing a piezostack device including multiple piezoelectric ceramic layers of a crystal-orientated ceramic and multiple electrode-containing layers laminated alternately. A raw material mixture is prepared in the mixing step, as an anisotropically shaped powder of oriented particles and a reactive raw powder are mixed. The anisotropically shaped powder and the reactive raw powder are then mixed in amounts at a stoichiometric ratio giving an isotropic perovskite compound, and a Nb2O5 powder and/or a Ta2O5 powder were added thereto. The raw material mixture is molded into a sheet shape in the sheet-forming step, while the crystal faces of the anisotropically shaped powder particles are almost oriented. An electrode material is printed on the green sheet in the printing step. The green sheets obtained after the printing step are laminated in the laminating step. The composite thus obtained is sintered in the sintering step, to give a piezostack device.
