Abstract
Provided is a load modulation amplifier including: a high frequency circuit board; and on the board, an input distribution circuit unit (DC) including: a distributor for dividing one input signal into two signals ISand IS; and a phase delay circuit formed on a signal line for the divided IS; a carrier amplifier (CA) including a first high frequency transistor for amplifying the IS; a peak amplifier (PA) including a second high frequency transistor and for amplifying the IS; and an output combination circuit (OCCU) including: a 90-degree phase delay circuit (90DC) formed on a signal line for output of the CA; a combiner for combining output of the 90DC and output of the PA; and an impedance conversion circuit for converting an output impedance of the combiner. The CA and the PA are directly connected to the OCCU without converting an output impedance.
