ET Products and System Solutions for…

Increased Battery Life

Reduced Case Temperature

Improved Signal Strength

Why ET?

In the past, a power amplifier (PA) was connected directly to the battery of a phone or an APT DC/DC converter. Both methods provide a higher voltage than needed to the PA, which is wasteful.

ET replaces these outdated methods by delivering a precisely controlled voltage to the PA, so the PA is always operating at its best efficiency.

ET dramatically improves the efficiency of the PA, reducing the current draw on the battery and eliminating heat due to PA inefficiency. ET also improves the fidelity of the PA at higher output powers, directly increasing transmit signal strength.
