摘要: The dual band code division multiple access radio of the present invention operates on frequencies simultaneously either transmit or receive. path by splitting intermediate frequency (IF) (103) and mixing IF to two different using synthesizers (140 145). receive (104) has RF channels (116 117) that are mixed with generated 145) summed into one strip. Thus can perform a soft hand-off between while communicating both base stations simultaneously. Additional paths be added if it is desired communicate more than
