Radar Front-End (RFE) Development Cycle• HXI has delivered a number of RFE prototypes and production units for various

programs, including helicopter landing systems. The prototypes were realized very quickly using HXI catalog components.

• The highly integrated assemblies require closely interactive engineering development efforts with the customer to assure that all system level requirements are met.

• Common LO distribution/upconversion packaging using MMIC/microstrip technologies.

• Waveguide downconvert mixer used for it’s high compression point and input power handling capabilities, with noise figure within one dB of using a MMIC LNA. (30 dB power handling advantage)

• Separate transmit power amplifier so future power improvements would not affect main transceiver packaging.

• Phase 1 (breadboard) and Phase 2 (pre-production) units flew in demonstrations for the U.S. Army and advanced the program to the next phase.

Transmitters – Receivers – Transceivers - Block Upconverters

HXI, LLC has provided a number of integrated subsystems for military customers, think tanks and commercial ventures as well. Transmitters, receivers, transceivers, block upconverters and test sets anywhere from a few GHz up past 100 GHz are all within our capability and experience.

• In April 2014, HXI began an effort to support “Microwave Nearfield Radar Imaging(NRI) Using Digital Breast Tomosynthesis (DBT)for Non-Invasive Breast Cancer Detection“. HXI’s partners in this development areNortheastern University and MassachusettsGeneral Hospital Radiology Department.

• HXI has developed a C-Band radar transceiver with multiple transmitters and receivers to facilitate the formation of images that can show the presence of cancerous material within the breast. Northeastern developed the signal processing and software to process the radar signals into the images. Mass General’s radiology experts will be consulting with Northeastern to tweak the design and help to present the radar concept and design to industry partners.

Breast Cancer Detection Radar

94 GHz Foreign Obstacle Detection (FOD) Runway Radar• HXI has completed a design working with a foreign government

technology development organization for a 94 GHz FOD radar to be used at airport runways.

• Dual aperture design with 4 x 1 aspect ratio antennas for accurate azimuth determination.

• DDS-based FMCW design with upconversion to 94 GHz and 2nd conversion for accurate IQ output.
