  • Method and apparatus for low-frequency bypass in broadband RF circuitry
    Patent number: 7221220
    Abstract: A method of processing an input broadband signal in RF circuitry includes extracting low-frequency components from the input broadband signal, processing the low-frequency components in low-frequency bypass circuitry, and adding the processed low-frequency components to the output of the RF circuitry to produce a combined output signal. Low-frequency bypass amplifier circuitry for bypassing RF circuitry includes a capacitor having a first terminal for receiving an input signal and a second terminal for connecting to an input of the RF circuitry, and a differential amplifier having two inputs respectively connected to the two terminals of the capacitor, and an output connected to an output of the RF circuitry. High-frequency components of the input signal pass through the capacitor and the RF circuitry, and low-frequency components pass through the differential amplifier and are added to the output of the RF circuitry to produce a combined output signal.
