Multiple frequency band information signal universal front end with adjustable analog signal path components
摘要:
A wireless device includes processing circuitry, a receiver section, a transmitter section, and an antenna. The processing circuitry determines a set of information signals of a RF Multiple Frequency Bands Multiple Standards (MFBMS) signal. The receiver section down-converts a portion of the RF MFBMS signal by one or more respective shift frequencies to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal from which the processing circuitry extracts data. The transmitter section converts a respective BB/IF information signal received from the processing circuitry by a respective shift frequency to produce a corresponding RF information signal and a combiner that combines the RF information signals to form a RF MFBMS signal. Each of the receiver section and the transmitter section may include analog signal path elements that are adjustable based upon characteristics of the RF MFBMS signal, the BB/IF MFBMS signal, and/or based upon signals carried therein, e.g., modulation type, SNR requirements, etc.
