A digital transmitter includes: a plurality of adjustable delay lines arranged to delay a plurality of digital input signals by a plurality of delay times to generate a plurality of delayed digital input signals respectively; a plurality of converting devices arranged to convert the plurality of delayed digital input signals into a plurality of converting signals respectively; and a calibration device arranged to adjust a delay time of at least one adjustable delay line in the plurality of adjustable delay lines to make the plurality of converting devices convert the plurality of delayed digital input signals at respective desire time points.

Digital transmitter and method for calibrating digital transmitter

The invention provides a high module carbon fiber and a fabrication method thereof. The high module carbon fiber includes the product fabricated by the following steps: subjecting a pre-oxidized carbon fiber to a microwave assisted graphitization process, wherein the pre-oxidized carbon fiber is heated to a graphitization temperature of 1000-3000&#xb0; C. for 1-30 min. Further, the high module carbon fiber has a tensile strength of between 2.0-6.5 GPa and a module of between 200-650 GPa.
