Abstract :
An UWB impulse radio (IR) transmitter comprising of standard emitter coupled logic (ECL) components is presented. It has a variable operating frequency ranging from 2-8 GHz and synthesizes Gaussian shaped B-/QPSK modulated impulses. The pulse width as well as the pulse position is variable in steps of 10 ps. This enables the use of the transmitter for laboratory purposes as test system for different IR modulation schemes including basic B-/QPSK, transmitted reference (TR) and pulse position modulation (PPM).
