Abstract
A communication apparatus includes a radio frequency (RF) apparatus. The RF apparatus includes an amplifier, and a signal detection circuit. The amplifier receives RF signals and amplifies those signals. The amplifier has an adjustable gain value. The signal detection circuit detects whether a received signal is an out-of-band radar signal depending on the gain value of the amplifier and a characteristic of the received signal.
