Abstract
A wide-frequency band quadrature bandpass-sampling receiver is provided. An RF signal received at the antenna is amplified by an LNA and filtered by an image-reject filter. The filtered RF signal is then frequency-shifted to an intermediate frequency which is located in between 1 GHz to 4 GHz. A quadrature bandpass-sampling analog-to-digital demodulator down-converts and digitizes the frequency-shifted signal at the intermediate frequency to baseband yielding a bi-level in-phase component and a bi-level quadrature component.
