Abstract:
The Stratospheric Water Inventory, Tomography of Convective Hydration (SWITCH) measurement concept is a spaceborne active microwave occultation sounder system for making two-dimensional tomographic atmospheric composition measurements with and unprecedented combination of vertical (~500m) and along-track (~10km) resolution. The measurement approach employs multiple small (e.g.,6U-CubeSat-class) transmitters orbiting in the same plane and flight direction as a separate (larger) receiver instrument. As these transmitters are required to operate within a small cube-sat form factors with limited payload weight and power, SWITCH leverages CMOS system-on-chip (SoC) technology from the mobile phone industry to implement the required electronics. This talk will discuss development of CMOS W-band LO system employed within the SWITCH system. Topics covered include the implementation and internal calibration of the SoC as well as packaging, testing, and evaluation.
