T/R Multi-Chip MMIC Modules for 150 GHz
Read More >>
A transmitting gain of 14 dB at 150 GHz has been demonstrated.
Modules containing multiple monolithic microwave integrated-circuit (MMIC) chips have been built as prototypes of transmitting/receiving (T/R) modules for millimeter-wavelength radar systems, including phased-array radar systems to be used for diverse purposes that could include guidance and ...Read More >>
Some Improvements in Utilization of Flash Memory Devices
Two developments improve the utilization
of flash memory devices in the
face of the following limitations: (1) a
flash write element (page) differs in size
from a flash erase element (block), (2) a
block must be erased before its is rewritten,
(3) lifetime of a flash memory is typically
limited to about 1,000,000 erases,
(4) ...

GPS/MEMS IMU/Microprocessor Board for Navigation
A miniaturized instrumentation
package comprising a (1) Global
Positioning System (GPS) receiver, (2)
an inertial measurement unit (IMU)
consisting largely of surface-micromachined
sensors of the microelectro-mechanical
systems (MEMS) type, and
(3) a microprocessor, all residing on a
single circuit board, is part of the navigation
system of a compact robotic
spacecraft intended to ...
