SIGNAL TRANSMITTER FOR WIDEBAND WIRELESS COMMUNICATION |
摘要 |
A signal transmitter for generating a wideband RF signal for use in, for example, a 60 GHz wireless area network, wherein a wideband (e.g 4 GHz) baseband signal is divided into a number of sub-signals (14) that can be synthesized in parallel, thereby relaxing the requirements of the mixed-signal and RF blocks. This division can be performed either in time or frequency and one DAC (12) is used for each sub-band (12). Where frequency division multiplexing is used to divide the baseband signal into sub-bands (14) the additional advantage is afforded whereby analogue adjustment of the gain in each sub-band (14) is possible, so as to compensate for wideband frequency selective fading in the channel. |
