    Design considerations of a generic wideband communication system differ significantly from its narrowband counterpart. In a wideband system, intermodulation distortion increases significantly, as the signal propagates through various active stages of RF/analog signal processing blocks. Thus, in contrary to the narrowband approach, it requires careful optimization of noise and linearity for a given... View full abstract»
