A WLAN transmitter capable of transmitting data signals modulated in accordance with an individual one of at least two different modulation schemes and corresponding methods and integrated circuit chips are provided. The WLAN transmitter contains a front end section having a low-IF topology and including a digital front end unit and an analog front end unit. The digital front end unit contains a first signal processing branch for processing transmission data signals modulated in accordance with a first one of said at least two different modulation schemes. The digital front end unit further contains a second signal processing branch for processing transmission data signals modulated in accordance with a second one of said at least two different modulation schemes. The analog front end unit contains one single signal processing branch for processing transmission data signals modulated in accordance with any one of said at least two different modulation schemes.
A WLAN (Wireless Local Area Network) transmitter capable of transmitting data signals modulated in accordance with an individual one of at least two different modulation schemes, said WLAN transmitter comprising a front end section having a low-IF (Intermediate Frequency) topology and including a digital front end unit and an analog front end unit, said digital front end unit comprising a first signal processing branch for processing transmission data signals modulated in accordance with a first one of said at least two different modulation schemes, and a second signal processing branch for processing transmission data signals modulated in accordance with a second one of said at least two different modulation schemes, and said analog front end unit comprising one single signal processing branch for processing transmission data signals modulated in accordance with any one of said at least two different modulation schemes.
