APPARATUS FOR CONVEYING INFORMATION IN A PORTABLE COMMUNICATION DEVICE

摘要

A portable communication device ( 100 ) includes a radio ( 102 ) and RF memory key ( 104 ) that allows both RF and baseband signals to be transported over the radio antenna port. A single wire memory device ( 134 ) is embedded into RF memory key ( 104 ) along with frequency diplexing circuitry ( 116 ) to transport single wire bus communications between the radio ( 102 ) and RF memory key ( 104 ) while RF is passed from the radio ( 102 ) to an antenna ( 150 ).
