NOVEL REMOVABLE CAST WALKER TO REDUCE SHEAR AND PRESSURE

Not Available Single-chip MMICs that perform all RF front-end functions of FM-CW radars are used as proximity sensors in the new generation of fuzes in artillery and mortar munitions. To extend this technology to proximity fuses in small to medium caliber munitions and sub-munitions, it is now necessary to develop novel techniques for lower power consumption and further miniaturization by expansion of scale of integration combining RF and signal processing circuits. This proposal describes Hittite's approach to develop a highly integrated chip for the low-power ultra-miniature proximity fuses. The proposed approach is based on Hittite's unique circuit techniques and newly emerging silicon and gallium-arsenide semiconductor processes. The new processes allow operation of silicon MMICs at higher frequencies and integration of signal processing circuits in GaAs, showing a promise of highly integrated multi-function mixed-signal ICs. The proposed program will lead to definition of optimum scale of integration, selection of the optimum process, and demonstration of the feasibility of the low-power ultra-miniature fuses. BENEFITS: Products to be derived from the proposed program are integrated sensors for proximity sensing, object detection, range sensing, etc. Commercial applications of those sensors include: vehicular sensors for approach control, blind-zone sensing, crash sensing, etc., area access control, liquid level control, traffic control, etc.
