Abstract (2. Language): 
A novel design of impulse radio ultra wideband (IR-UWB) pulse generator with two models of 2-Gbps and 3-Gbps is presented. Bi-phase modulation (BPM) and frequency modulation (FM) techniques are used together with the initial generated pulse of 1 ns to achieve the higher speeds. The generated pulse spectrum complies with the UWB Federal Communication Commission (FCC) regulations of indoor mask, working between 3.1 - 10.6 GHz with power of less than -41.3 dBm/MHz. The proposed low cost - pulse generator is based on simple structure of shaping continuous sine wave signal to UWB pulses, where the generator can be fabricated through a discrete circuit. The filtering process is achieved by the designed stepped-impedance low-pass microstrip filter. Based on the generated pulse characteristics, the generator can utilize the Frequency Division Multiple Access (FDMA) to connect two users simultaneously. The design results have been simulated using Advance Design System (ADS) software.
