Two simple and compact ultra-wideband, ultra-short-pulse transmitters have been developed using a monolithic microwave integrated circuit (MMIC). These pulse generators include a digital approach for the pulse forming based on a logic gate. They produce pulses with a variable width as low as 65 ps and rise and fall time about 25 ps (measured). The pulse position modulation (PPM) with pulse frequency rate (PRF) from frequency below 1 MHz to several GHz is also possible. Finally, an analog filtering solution for its shape is proposed in order to be compliant with the FCC part 15 frequency mask
