Abstract
A millimeter wave power amplifier device has multiple millimeter wave power amplifier circuits. Each millimeter wave power amplifier circuit includes a transistor, a first serial connection resonation unit, a second serial connection resonation unit, multiple first frequency band adjustment units and multiple second frequency band adjustment units. The transistor has a first end connected with an input end, a second end connected with a grounding end and a third end connected with an output end. Each of the first and second frequency band adjustment units has a switch member and two storage members. The switch member and the storage members of the first and second frequency band adjustment units are serially connected. The millimeter wave power amplifier device can achieve multi-frequency band adjustable effect to lower the cost.
