The present invention is first balun impedance for applying a predetermined first output power to convert to the desired gain in accordance with an impedance change which varies according to the input signal applied to the oscillator, the oscillator for applying an input signal to turn the number of built-in inductors a transformer, a first power supply, said first balun power for amplifying a first output power, the impedance transformer is in the amplifier, a first output power amplifier in said power amplifier for supplying the operation power to the first balun impedance transformer depending on the turn number of built-in inductors receiving in accordance with the variable impedance changes are converted to the desired gain by supplying the operation power to the predetermined second output power to the second balun impedance transformer and the second balun impedance transformer that is the second relates to a balun and the RF choke a high output power for a combined low-frequency amplifying apparatus comprising an power supply, can reduce the size of the power amplifier than the prior art, which the band, and the entire system when applied in the same place and channel transceiver It can achieve the downsizing and is the effect of the number of the ferrite core (ferrite core) reduced by half occurs in the price aspect. In addition, RF signal is also to minimize the leakage electric power generated by the inductor (inductor) according to the number of inductors (inductor) decreases gain hyogwaeul improved efficiency.
