Important Technological Developments

1. Transceivers to transmit at 10, 19, and 32 GHz and receive at 12, 21, and 35 GHz
•	The entire system is full-duplex so that the transmit and receive links operate simultaneously using the same antenna array.
•	The system architecture developed allows the entire phased array to operate using a single low-loss broadband phase shifter.
2. Multi-band phased array radar prototype operating from 3 to 20 GHz.
•	The new phased array technology provides significant reduction in DC power consumption, size, volume and cost. The technology enhances system efficiency, reliability and c ompactness.
•	The technology was developed in collaboration with Texas A&M University and demon strates electronically beam scanned antenna arrays in 2-D planes at X-band (8 to 12 GHz) in AZ and EL planes, and beam scanning capability from 8 GHz to 35 GHz.
