<p>A master oscillator (100) generates a first tone that has a frequency or notional carrier frequency of the ultra wideband signal. The comb generator (102) has three outputs that correspond to second, third, and fourth tones. After the comb generator (102), the signals pass through filters (122, 132, 142), phase trimmers (124, 134, 144), and amplifiers (116, 126, 136, 146). Finally the tone signals are all put into a combiner network (150).</p> |
