Title:
Super-wideband-frequency-modulation machine
Document Type and Number:
Japanese Patent JP5905641
Kind Code:
B2
Abstract:
An ultra-wide band frequency modulator is disclosed. The frequency modulator includes a direct modulation phase lock loop that receives a small component. The frequency modulator also includes a delay module that produces a plurality of delay lines. The frequency modulator further includes an edge selector that receives a large component and the plurality of delay lines.
