Abstract
A wideband radio receiver provides a complex baseband signal by normalizing an IF signal using a limiting amplifier. The normalized IF signal is applied to a complex sampling circuit to provide normalized I and Q components. The limiting amplifier provides an RSSI signal representing the received signal amplitude. The RSSI signal, which is sampled at the same rate as the normalized IF signal, is combined with the normalized I and Q components, to provide I and Q components of the baseband signal.
