Abstract
There is disclosed an improved multi-mode, spread spectrum digital radio comprising: a radio frequency (RF) subsystem for converting spread spectrum digital signals comprising voice and data communications between baseband and RF signal frequencies in response to control signals; a digital signal processor based baseband subsystem having isolation interface means bidirectionally coupled to the RF subsystem for minimizing RF and baseband signal interference; the baseband subsystem operable to control the mode of operation, to provide interface control signals to the RF subsystem based on the mode, to format the transmitted and received digital signals, and to provide external controls and status to a user to enable selectable mode switching.
