Abstract: We have developed a novel opto-electronic transceiver designed to provide a jam-resistant, high-security, low-power RF communications link. By employing picosecond photoconductivity and a time-hopped spread-spectrum architecture, the transceiver can realize multi-octave instantaneous RF bandwidth. The design is capable of processing gains well above those of existing spread-spectrum communications systems. Hence, significant jam resistance is achievable with a minimum of RF power. The transceiver is particularly well suited to serve as the physical layer of a packet radio system and can be packaged in a hand-held unit with Q-switched diode laser technology. We present results from an opto-electronic digital spread-spectrum data link that demonstrate some of the capabilities of this approach. Abstract Number(s): B9706-6250-019
