Title: Substrate for electric power and electric power amplifier for high frequency
Inventor: MAEDA MASAHIRO
IPC: H03F3/60
Filed: 1993-07-28
Abstract: PURPOSE:To decrease the number of assembly processes, and to miniaturize volume by using a ceramic substrate constituted of aluminum nitride as main components, and arranging a power transistor chip on the substrate without mounting it on a package. CONSTITUTION:A power FET 1, chip capacitor 12, and chip resistor 13 are mounted on an aluminum nitride substrate 16, so that a power amplifier for high frequency can be constituted. The power FET 1 is the FET of GaAs, and the back face is ground in order to suppress the increase of channel temperature in operation. Those FET 1 and the chip parts 12 and 13 are electrically connected with a microstrip line 11. The thermal conductivity of the aluminum nitride is superior almost ten times to that of alumina, and at the time of using the substrate 16, the increase of the channel temperature can be suppressed, and the decrease of an output power can be reduced. Also, a dielectric constant is high, and the length of the strip line 11 constituting a matching circuit can be made short. Thus, the miniaturization of the amplifier can be attained, and the miniaturization of the mounting area can be attained not by package- mounting but by chip-mounting the FET 1.
