Abstract
Provided is a power device having a connection structure compensating for a reactance component, in which transistors are arranged and connected to minimize deterioration of transistor properties caused by heat by compensating for a reactance component causing a phase difference due to transmission lines used for connecting a plurality of transistors in parallel such that the power device to be used for a high-frequency power amplifier outputs high power, and transmitting heat generated by high output power to a heat sink to be dissipated.
