TECHNICAL ABSTRACT (LIMIT 200 WORDS)
This proposal is specifically written to address the need for improved Ka-band T/R modules. The solicitation calls for investigation and development of core technologies that will significantly improve T/R module performance. Improvements needed include reduced power consumption, mass, and size. Hittite Microwave Corporation is a fabless semiconductor company that has been developing microwave monolithic integrated circuits (MMICs) for over 19 years. Hittite proposes three possible areas of focus for the SBIR program, transmitter power amplifiers, receiver integration or complete T/R functionality. By far the largest contributor to the size and weight of a T/R module is the power amplifier. Both GaN and MHEMT are new technologies that have the potential for substantial improvement over incumbent PHEMT technology. MHEMT is most suited to power levels below 4 Watts reverting to the higher power density GaN technology at higher power levels. Both MHEMT and advanced SiGeBiCMOS technologies such as IBM 8HP can be consider for receiver functions. Finally MHEMT strikes a good balance as a single technology platform for a moderate power level (<2 Watt transmit) T/R MMIC/module at 35 GHz. The proposal includes a technology summary as well as basic design considerations and examples of LNAs, PAs and phase shifters.

POTENTIAL NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The proposed program will lead to a family of MMIC-based products useful in the commercial communication bands for such applications as point to point digital radio links and systems operating in the frequency range of 30 to 40 GHz. Hittite expects to develop a market for MMIC products operating in those bands.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (LIMIT 150 WORDS)
The proposed program will lead to a family of MMIC-based products useful in the commercial communication bands for such applications as point to point digital radio links and systems operating in the frequency range of 30 to 40 GHz. Hittite expects to develop a market for MMIC products operating in those bands.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
