摘要: A multiple-mode receiver incorporating direct conversion (processing received signals using intermediate frequencies within the same frequency range as signal bandwidth) rather than superheterodyne circuitry, allowing hardware components to be re-used replicated for each band. Various embodiments are disclosed in which low pass filters, mixers, quadrature generators, oscillators, and amplifiers re-used.
