    摘要： An insulated gate semiconductor device, which improves high frequency characteristics by reducing the resistance of a path from a gate bonding portion to each gate and eliminating an unbalance in resistances of respective gates, and which obtain a higher output by eliminating a limitation in current capacity due to the thickness of a first metal layer. In this insulated gate semiconductor device, a first aluminum layer is connected in parallel onto a gate electrode made of polycrystalline silicon. The adjacent gates, each having such a double layer structure, extend outside channel regions and are connected to each other. A lead-out electrode of a second aluminum layer is connected to the center of the connection portion of the adjacent gates through an opening portion. A gate bonding portion is provided at the center of the lead-out electrode. Each of source and drain electrodes is also of a double layer structure having the first aluminum layer and the second aluminum layer.

    摘要： A radio frequency power amplifier module for a dual-band type mobile communication apparatus that can transmit and receive the first frequency f1 and the second frequency f2 (f2=2×f1) is structured as explained below. This radio frequency power amplifier module for dual-band type mobile communication apparatus is comprised of a drive stage amplifier having the gain peaks at f1 and f2 with a matching circuit and a radio frequency power output circuit including a radio frequency power output transistor. The output circuit is constituted of a transmission line connected to the drain end of the output transistor, a parallel resonance circuit connected in series to the transmission line to resonate at the harmonics in the frequency twice the frequency f2, a series resonance circuit provided between one end of the resonance circuit and the ground to resonate at the harmonics in the frequency twice the frequency f2 and an output matching circuit provided in series to the other end of the parallel resonance circuit for the matching with f1 and f2. The transmission line is set to terminate at the drain end for the even number order harmonics of f2 with the reactance existing at the drain end and a circuit element constant forming the parallel resonance circuit is set to open at the drain end for the odd number order harmonics of f2 with the series resonance circuit, transmission line and reactance existing at the drain end. With the structure explained above, since harmonics power can be controlled through control of the predetermined harmonics, high efficiency and reduction in size of the radio frequency power amplifier module can be realized.
