In a wireless receiver apparatus including a gain control amplifier for controlling a gain of a reception signal, a maintaining device compulsorily maintains the gain of the gain control amplifier at a predetermined fixed value only in a predetermined specified interval. The maintaining device includes a latch circuit for maintaining a gain set value immediately prior to the specified interval. A start timing of the specified interval is determined by an edge of a predetermined timer start signal, and a duration of the specified interval is determined on the basis of a count of a predetermined timer clock signal and a count of a predetermined timer count set bus signal.
