The analog filter should have about 30dB rejection at 30MHz. With DAC who have internal interpolation (up-sampling) the filter specification could be relaxed significantly.OFDM WaveformDAC samplingrate : 40Ms/sFirst unwantedImage.OFDM convolutedwith sampling Impulse train (sin(x)/x)Multipleunwanted OFDMimagesWantedOFDM WaveformNational Semiconductor CorporationAdvanced Wireless Technology GroupRF Test Report5-December-2002Stefan [email protected] 11 of 16Transmitter, RF signal with WLAN OFDM BPSK 800bit packetTX RF signal before going into
