TelASIC Communications is pleased to submit an SBIR proposal for the Mixed Signal for Multifunction RF (Radio Frequency) Sensor. This proposal includes the investigative study of the development of a flexible and affordable digital synthesis approach capable of generating waveforms for high range radars and low probability of intercept communication applications. TelASIC is proposing to investigate the highest level of integration on a single chip. TelASIC is proposing to explore the feasibility of a novel RAM/ROM hybrid delta-sigma DDS (Direct Digital Synthesis) with multi-bit DAC on a single chip. Two versions will be considered: The first will clock a multi-bit DAC at greater than 20 GHz for a Nyquist of greater than 10GHz, and the second version will have a higher resolution DAC upconverted to greater than 10 GHz. The feasibility of the multiplexed DAC clocked at greater than 20 GHz and capable of synthesis at carrier frequencies over 10 GHz with 1 GHz of instantaneous modulation bandwidth, using the IBM SiGe 7HP or 8HP BiCMOS processes, will be investigated. In addition to the ultra high speed bipolar capability, special considerations will be given to maximize the utilization of the advanced CMOS in the SiGe BiCMOS, DRAM and SRAM for a low power and low cost monolithic solution.
Benefits: Satellite HDTV, air traffic control and weather radars.
