Abstract
A multi-finger transistor includes unit transistors each including a first terminal electrically connected to a reference potential, a second terminal that receives an RF signal and a bias current, and a third terminal that outputs an amplified signal; a common input terminal electrically connected in parallel to the second terminals of the unit transistors and that receives the RF signal; a common bias terminal electrically connected in parallel to the second terminals of the unit transistors and that receives the bias current; a common output terminal electrically connected in parallel to the third terminals of the unit transistors and that outputs the amplified signal; and first resistance elements each of which is electrically connected between the common input terminal and the second terminal of a corresponding one of the unit transistors and each of which cuts a DC component of the bias current.
