Technology Barrier

TETRA standard defined Linear

Terminal has to use Linear PAM

Linear PAM needs High voltage operationdefined Linear

transmission Technology ;

use Linear PAM and Cartesian Feedback Loop.

High voltage operation at least 7.2V

(2 cell battery)ACP : -60dBc

Th t’ h ti l t bl h t bThat’s why conventional portables have to be Heavy & Bulky with poor Efficiency.

3. Technology Innovations

Single Cell Operation for Light weight.

Simplify Architecture for cost savings.

Antenna Upgrade for performance.
