Constant-amplitude wave combination type amplifier
Abstract
A constant-amplitude wave combination type amplifier includes a first amplifier (1, 41) outputting a first amplified output (kA), and a second amplifier (2, 42) outputting a second amplified output (kB). The constant-amplitude wave combination type amplifier also includes a first constant-amplitude wave generating circuit (43) for combining an input wave (X) and the second amplified output from the second amplifier and for generating a first constant-amplitude wave (A) which is input to the first amplifier, and a second constant-amplitude wave generating circuit (44) for combining the input wave and the first amplified output from the first amplifier and for generating a second constant-amplitude wave (B). Further, the constant-amplitude wave combination type amplifier includes a wave combining circuit (45) for combining the first and second constant-amplitude waves and for generating an output wave.
