摘要： An AGC processing portion receives a burst signal of each received frame, and measures its received power level to perform gain control of a variable gain amplifier. Unlike a conventional wireless receiving device, a digital signal from an A/D converter is directly supplied to the AGC processing portion, without passing through an FIR filter. Accordingly, the input timing for the AGC processing portion does not include a delay due to the FIR filter, and an amplitude value can be adjusted to be appropriate from the leading part of each frame, suppressing the occurrence of a reception error due to AGC processing.

摘要： A signal processing circuit receives an output of a modulation circuit to perform amplification, filtering and mixing on the output so as to generate a signal having a selected frequency bandwidth. A modulation signal output control circuit refers to a table to specify the level of the signal output from the modulation circuit that corresponds to the selected frequency bandwidth of the transmission signal, and instructs the modulation circuit to set, to the specified level, the modulated signal that is to be output. An AGC amplifier amplifies the output of the signal processing circuit to a reference level. Here, the table defines the correspondence in such a manner that, as the frequency bandwidth of the transmission signal is larger, the level of the signal to be output from the modulation circuit decreases.
