Patent ID: 7162218

Claim:
A multi-carrier direct conversion receiver for receiving and processing a multi-carrier radio frequency (RF) signal, comprising: an antenna for receiving the multi-carrier RF signal; an RF amplifier which provides an interface between the antenna and a demodulator, the RF amplifier configured to amplify the received multi-carrier RF signal; the demodulator coupled to the RF amplifier and configured to convert the multi-carrier RF signal into in-phase (I) and quadrature (Q) baseband signals; first and second baseband stages, each stage comprising a low pass filter and amplifier, and the first stage configured to process the I baseband signal and the second stage configured to process the Q baseband signal; first and second analog to digital converters, the first converter configured to convert the I baseband signal to a digital I signal, and the second converter configured to convert the Q baseband signal to a digital Q signal; and a direct conversion circuit, connected to the analog to digital converters, for converting the digital I and Q signals into a plurality of channel signals.
