Abstarct Amplification is one of the most basic and prevalent RF/Microwave circuit functions. This paper describes the design of an 11 GHz PHEMT ATF-36077 microwave amplifier. The amplifier is manually designed using conventional technique, Smith chart was used to do a matching of the input and output of the amplifier. A completed design of the amplifier was optimised using Hewlett-Packard Adva...

Data collected by the C band ERS-2 wind scatterometer (EScat), the Ku band ADEOS-1 NASA scatterometer (NSCAT), and the Ku band SeaWinds on QuikScat (QSCAT) satellite instruments are used to illustrate spatiotemporal variability in snow accumulation on the Greenland ice sheet. Microwave radar backscatter images of Greenland are derived using the scatterometer image reconstruction (SIR) method at...

A design of microstrip patch antenna gap coupled with two parasitic elements on its non-radiating edges and a single parasitic element on its radiating edge for the operation in X band and Ku band is proposed here. The parasitic elements are partially shorted. This design is giving an impedance bandwidth of 4.967GHz. This antenna is operating over a frequency range of 11.2334 to 16.0431 GHz wit...

We present Ku-band backscatter signatures of snow for applications to global snow monitoring with NASA Scatterometer (NSCAT) on the ADEOS satellite and the SeaWinds scatterometer on the QuikSCAT satellite. We carried out the 1999 Alaska Snow Experiment to study the relation between Ku-band backscatter and snow physical properties. The experimental results are applied to interpret backscatter da...

The large-time asymptotic behavior of real-valued solutions of the pure initial-value problem for Burgers' equation u t + uu x ? u xx = 0, > 0, is studied. The initial data is of the form u 0 (x) = nx 1+x 2 + u 1 (x), where n 2 R and u 1 2 L 1 (R). Eberhard Hopf H] considered the case n = 0, and the case ku 1 k L 1 == + jnj suuciently small was considered in D]. Here we study the general case. ...
