ABSTRACT:
The transmission apparatus according to the present invention can reduce transmission output noise leaking into the receiving apparatus even when the transmission apparatus is applied to wireless equipment using the W-CDMA scheme. Transmission apparatus (100) has bypass circuit (101) and bypass control circuit (103) that inputs an RF phase signal to power amplifier (14) via amplitude adjustment circuit (16) when bypass circuit (101) and power amplifier (14) are operated in non-saturation mode, and that inputs the RF phase signal to power amplifier (14) via bypass circuit (101) when power amplifier (14) is operated in saturation mode.
