Methods and systems relating to ultra wideband transmitters

A wireless device comprising:

• an antenna;
• a radio frequency (RF) circuit;
• a memory;
• and
• a control circuit for controlling operation of the RF circuit in dependence upon data stored within the memory;
• wherein
• data stored within the memory comprises a plurality of masks;
• each mask of the plurality of masks defines an output power spectrum for the wireless device and a configuration for each pulse of a plurality of N pulses to be generated by the RF circuit for transmitting a bit of data to be transmitted by the wireless device;
• the configuration for each pulse of the plurality of N pulses defines a predetermined frequency of a plurality M frequencies, a predetermined amplitude, and a predetermined pulse length;
• N≥2 and M≥2;
• M and N are integers;
• and
• at least one of:
• the output power spectrum defined by each mask of the plurality of masks does not overlap one or more predetermined frequencies associated within one or more predetermined wireless standards such that the wireless device operate without filtering of a generated RF signal to be transmitted;
• and
• the output power spectrum defined by each mask of the plurality of masks comprises notches at one or more predetermined frequencies associated within one or more predetermined wireless standards such that the wireless device operate without filtering of a generated RF signal to be transmitted.
