Receiver circuit |
摘要 |
Interruption of a reception signal is achieved by placing a first low noise amplifier into the sleep state, and short-circuiting a shunt switch provided between differential input terminals of a second low noise amplifier during a DC offset canceling period. Further, an antenna switch is switched to a circuit system where DC offset canceling is not performed for preventing the input of the reception signal to a circuit system where DC offset canceling is performed.
