| 摘要 |
<p>The invention relates to a wideband communications receiver (1), especially a receiver in a wireless local area network, comprising: - an antenna interface module (RFM) including a low noise amplifier (3, 3.1, 3.2) connected to an antenna (2, 2.1, 2.2); - an analog front-end section (AFE) including: a preceding radio frequency amplifier (5); a direct down-converter (6) for down-conversion of amplified radio frequency signals (f^) directly to baseband into differential IQ signals (IQ); a succeeding amplifier (8.1, 8.2) for amplifying the differential IQ signals (IQ) into saturation; - an baseband controller (7) directly processing the amplified IQ signals (IQ) bitwise.</p> |
