An electronic circuit according to various embodiments may comprise: a switch circuit, wherein the switch circuit may comprise: a first switch connected to a first port and a second switch connected to a second port, the first and second switches being connected in series with each other; a first parallel switch connected to a node between the first switch and the second switch; and a first shunt inductor connected to the node between the first switch and the second switch and configured to cancel a parasitic capacitance component of the first parallel switch.

Electronic circuit and power amplifier comprising same

A vector sum circuit and a phase controller including the vector sum circuit are provided. The vector sum circuit includes an amplifier configured to amplify an input orthogonal signal by using a first metal oxide semiconductor field effect transistor (MOSFET), and a self body-biasing circuit comprising a resistor. The self body-biasing circuit is configured to connect a drain and a body of the first MOSFET to reduce a voltage connected to the body as a current at the drain increases.
