Abstract:
A power amplifier using an equivalent transformer is provided. The power amplifier includes amplifiers and T lines having first terminals connected to the amplifiers and second terminals connected to output sides. Accordingly, powers are combined using the equivalent transformer in the power amplifier, such that an insertion loss can be reduced and thus degradation of output power efficiency can be prevented.
