Multi-Channel, Wideband, 4-40 GHz Tuner for TUAV SIGINT in SiGe (9603)

Q-DOT proposes to develop a Multi-channel, wideband, 4-40 GHz tuner for TUAV SIGINT Payload in advanced, 210 GHz SiGe. The TUAV platform demands small size and low power consumption. IBM's 8T SiGe BiCMOS process has been developed around its recentlydemonstrated 210 GHz HBT. The 8T BiCMOS process enables the integration of the multi-channel receiver on a single, silicon chip at low cost and with low power consumption. Heretofore, 4-40 GHz circuitry required expensive, high-power, hybrid circuitscomprised of discrete GaAs chips. Phase I will result in a preliminary design of a highly integrated, multi-channel 4-40 GHz Tuner. Under the option, one (or more), of the critical subcircuits will be conceptually designed in the 8T BiCMOS process toassess its performance. Key subcircuits will be built in Phase II leading to the development of the complete Tuner under Phase III. Cost, size and power will all be reduced by realizing the 4-40 GHz multi-channel Tuner in advanced SiGe BiCMOS technology inplace of hybrid circuit built with GaAs chips. Commercial markets include broadband communications, satellite communications and broadband, wireless networks.
