Abstract
N (n is an integer more than one) number of transistors are connected in series in an order from a first transistor to an ntransistor from a first terminal to a second terminal. First to nnodes are connected to gates of the first to ntransistors. N number of resistance elements are connected in series in an order from a first resistance element to an nresistance element from a bias terminal to the nnode. The first resistance element is connected between said bias terminal and said first node, and the kresistance element (k=2 to n) is connected between the (k−1)node and the knode. Thus, a high frequency switch circuit can reduce an area of the whole gate bias resistances.
