Ultra-wideband (also known as uwb, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum.
In this thesis a two-stage architecture is used to obtain low noise figure, high linearity, high gain, and stability for the lna for the bipolar design, noise. An rf cmos implementation of an adaptive filter for narrow-band interferer suppression in uwb systems by markus both a thesis presented to the faculty of. Since ultra-wideband covers a wide range of frequency, it exhibits challenges in the design of building blocks, receiver front-end in particular the scope of this thesis. The goal of this thesis is to explain the fundamentals of microwave low noise amplifier (lna) design for use in the ultra wide frequency band (uwb), to illustrate and discuss some of the tradeoffs we are faced upon during the design phase of making a uwb lna in a modern. Low noise amplifier design for dense phased arrays wideband noise and input matching topologies to have an lna do thesis at astron and his guidance and.
For the broadband technologies and particularl y ultra-wideband (uwb) system, designing the lna becomes more challenging this ma ster thesis mainly focuses on. Wideband lna topology like common base or common emitter with feedback could support this coverage with relatively low noise figure, especially for advanced bjt structure like sige heterojunction bipolar transistor with a cutoff frequency of. This paper deals with the design of low noise amplifier using modfet for wireless communication the proposed lna will be operating at 6 ghz and uses two stages for improved gain and low noise figure.
