Classification: H01L,H03F

Abstract:
A high frequency circuit, comprising:a high output amplifier cell block configured to amplify input signals at a time of high output power, in which a DC power source voltage is supplied in parallel to first amplifier cells that are connected in parallel AC-wise with respect to input/output signals; a low output amplifier cell block configured to amplify the input signals at a time of low output power, in which the DC power source voltage is supplied in series to second amplifier cells that are connected in parallel AC-wise with respect to the input/output signals; a first connection unit configured to connect input sides of the high output amplifier cell block and the low output amplifier cell block with an input terminal from which the input signals are entered; and a second connection unit configured to connect output sides of the high output amplifier cell block and the low output amplifier cell block with an output terminal to which output signals are outputted.
