Design of 3.1–5.1 GHz pulse generator for UWB communications

Abstract

In this study a novel architecture of Ultra Wide Band generator is explained. This architecture is the major important component in the generator Ultra Wide band communications systems. The new generator is consists of oscillator, multiplier and triangular pulse generator. This new study of generator is consists by multiply the triangular pulse signal envelope with a sinusoidal signal in the aim to produce the nanosecond pulse. This new architecture generator circuit produces a short signal wave which is characterized by a bandwidth of 2 GHz, centered frequencies of 4.1GHz, and limited of -41.3 dBm/MHz the Power Spectral Density (PSD) is. The maximum amplitude is 154 mV, the pulse is during of 1 nanosecond and the pulse repetition period (PRP) is 10 ns. This new study focus on designing of ultra wide band generator component using the tool Agilent Advanced Design System.
