Abstract
In a wireless reception circuit, an LNA amplifies an input signal, and a mixer mixes the output of the LNA with a local oscillation signal. The output of the mixer is filtered by a first filter circuit, and the signal strength is detected by a first signal strength detection circuit. The output of the mixer is also filtered by a second filter circuit via an attenuator, and the signal strength is detected by a second signal strength detection circuit. The signal strength detected by the first signal strength detection circuit and the signal strength detected by the second signal strength detection circuit are added up to obtain the signal strength of the input signal.
