A new bi-phase modulation(BPM) pulse UWB transmitter manufactured by discrete components is designed. The transmitter consists of mono-polar sub-nanosecond pulse generator, bipolar pulse generator, and high speed microwave switch. The transmitter transmit positive and negative pulses when controlled by clock signal as well as data ‘1’ and data ‘0’, respectively. Experimental results show that the generated pulse width is below 400 ps, the bandwidth is more than 1.5 GHz, and the data rate is up to 50 Mbps. It can be used in the pulse UWB(ultra-wideband) communication systems.
