New indium phosphide integrated circuits will soon be available for the new satellite and terrestrial broadband systems planned for 60-to-90-GHz range and for new frequencies opneing up above 100-GHz. TRW Space and Electronic Systems. is building a 4-inch indium phosphide wafer line at its Redondo Beach, Calif., headquarters to sell the chips on the commercial market.
TRW claims indium phosphide is one of the few materials capable of working at the new extreme frequency range. Initial devices will be low noise RF amplifiers, digital frequency synthesizers and frequency dividers. TRW is also considering licensing its indium phosphide chip technology or partnering with other suppliers in expanding the indium phosphide market.
