Abstract
A semiconductor power amplifier of an embodiment includes: a plurality of unit FETs disposed in parallel in a direction of a substantially straight line connecting source electrodes of the unit FETs; a first via hole which connects the two source electrodes positioned between adjacent ones of the unit FETs in common and an RF ground electrode; and a second via hole which connects the source electrode on a side having no adjacent unit FET and the RF ground electrode. Each unit FET includes: a gate electrode which connects gate finger electrodes and leads out the gate finger electrodes; a drain electrode which connects drain finger electrodes disposed facing the gate finger electrodes and leads out the drain finger electrodes; and two source electrodes which connects source finger electrodes disposed facing the gate finger electrodes and lead out the source finger electrodes to opposing sides in a widthwise direction thereof.
