High AJ RF ASIC

Nu-Trek and Raytheon propose to develop a rad-hard-strategic High Anti-Jam (AJ) RF ASIC. Part will be PRF 38585 qualified and sold as OEM product for incorporation in GPS receivers. Presently, ALL High AJ RF Sections are made of DISCRETE components. Also, there are no GPS receivers that are rad-hard-strategic. High AJ RF Section with external filters constitutes an entire RF Section and is 1/5 the volume of a discrete RF Section with comparable capability. (ASIC will be 64-pin part, < 0.2 cubic inches). AJ capability will be 70 dB with internal 2-bit ADC and 120 dB with external 12-bit ADC. (Attenuation by Antenna, RF Section, and Digital Section are additive.) Codes and applications supported include C/A, P(Y), M, and SAASM. The High AJ RF ASIC will operate simultaneously at two frequencies or support two channels of adaptive antenna nulling. A number of two-channel devices can be used for a larger number of channels and/or more complex adaptive antenna electronics. Advanced RF ASICs will feature up to seven channels per device. This will enable the receiver to perform adaptive antenna spatial signal processing. Primes, such as Lockheed Martin, Raytheon, and Honeywell are interested in using part.
