How would you like to design circuits with perfectly shielded, low-loss, purely TEM broadband transmission lines, which could be stacked next to and on top of each other with no coupling? The lines can be tens of centimeters long, cross at multiple levels and at any angle, and holes...

As linear modulation and demodulation is adopted in communication systems for spectrum efficiency, the system performance is limited due to nonlinearity, particularly in the power amplifier. The nonlinearity of a system can be explained as AM-AM, AM-PM, intermodulation distortion (IMD) and adjacent channel leakage ratio (ACLR). Several linearizing techniques...
