Abstract
PURPOSE:To minimize the variance in the amplification characteristic of a high frequency amplifier due to the deviation of a chip packaging position by providing a projection formed by a minute marker or a microstrip line, and packaging a chip while using the marker or the projection as a guide. CONSTITUTION:The marker 3 provided to a prescribed part on microstrip lines 2a, 2b closest to the amplification chip 1a or a rectangular projection 4 is formed on the microstrip lines 2a, 2b and in packaging an amplification chip 1a in connection with the microstrip lines 2a, 2b, the chip is connected to the marker 3 or the projection 4 on the microstrip lines 2, 3. Thus, it is possible to minimize the variance of the amplification characteristic of the high frequency amplifier.
