July 13, 2001 Mr. Frank Coperich Federal Communicatio ns Commission Office of Engineering & Techno logy 7435 Oakland Mills Road Gate A Columbia MD 21046 Dear Mr. Frank Coperich: This enclosure co ntains the two-tone data for CDMA and TDMA that is pending under 731 Confirmation Number EA89075. As per our discussion under Correspo ndence ID 4035, the two- tone data criteria was to provide two-tones that wo uld produce 3 rd order IMD’s that would fall out of the 869-894 MHz transmit cellular band and the other 3 rd order IMD’s that would be in the 869- 894 MHz transmit band. The data provided has both input and o utput plots for CDMA & TDMA. It is our understanding that this is the data needed to complete the type approval pending o n the amplifier model FFPA8689-35. If there are any other questio ns, please feel free to contact us. Best Regards Patrick K.
