A single stage wideband amplifier based on an AlGaN/GaN HEMT power cell with a total gate-width of 16 mm matched to 50 Ohm has been successfully developed and characterized by use of a single-carrier W-CDMA signal. A very wide bandwidth of more than 1.7 GHz covering several mobile radio frequency bands within Land S-band with peak output power levels up to 44 dBm has been demonstrated with meet...

The study aimed to determine the impact of sound land use management to the runoff in Kabuntalan, Maguindanao in Tamontaka river basin. This was done through simulation and the comparison of the three land cover scenarios such as 2015 land cover, 2025 projected land cover and desired land use to determine its difference in terms of runoff. Hydrologic Engineering Center-Hydrologic Modeling Syste...

This Paper uses MODIS data to monitor and evaluate cultivated land changes in Yangtze River Delta region. Firstly, In order to validate the veracity of the classification results by MODIS, Hangzhou city is selected as the experimental area, Spot5 and Landsat scenes in 2001 and 2005 are collected and used to conduct initial validation exercises to assess the quality of land use classification re...
