Phase correction circuit for radio communication apparatus |
摘要 |
A phase correction circuit for a radio communication apparatus includes a variable gain amplifier and phase correction unit. The variable gain amplifier amplifies a transmission/reception signal on the basis of a gain variably set in accordance with a gain signal. The phase correction unit has a phase characteristic opposite to that of the variable gain amplifier, corrects the phase of the transmission/reception signal on the basis of the gain signal supplied to the variable gain amplifier, and cancels a phase change of the signal caused in the variable gain amplifier. |
