dc.description.abstract	The design philosophy and recommended standards for PN DDOR transponders are proposed in RFM 20-04. The referenced document illustrates how to pick a chip rate, roll-off factor, and other PN parameters for a PN DDOR transmitter. The document also proposes various recommendations for these parameters. This document expands upon RFM 20-04 and presents two PN DDOR transmitters that were designed and tested at JPL. First the IRIS cubesat radio is presented with an 8 MHz spread spectrum DDOR signal. Next the Univeral Space Transponder (UST) transmitter is presented with a 32 MHz spread spectrum DDOR signal. These transmitter designs show that the proposed recommendations are reasonably implemented with current technology.
