Abstract
A UWB pulse emitter includes an H-bridge having first and second branches in parallel, a first end common to the branches being connected to a first amplitude control module to regulate a high voltage, a second end common to the branches being connected to a second amplitude control module to regulate a low voltage. A first envelope control module controls the shape of the positive portion of a UWB pulse and a second envelope control module controls the shape of the negative portion of this pulse. Each branch comprises first and second switches for respectively switching the high voltage to a first or second input of the first envelope control module and the low voltage to a first or second output of the second envelope control module. Centre taps of the branches, between which the UWB antenna is connected, connect the outputs and the inputs of the control modules.
