ET Products and System Solutions

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ET replaces these outdated methods by delivering a precisely controlled voltage to the PA, so the PA is always operating at its best efficiency.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

These Products Offer The Highest Performance with No PA Limitations

Q845 Q845 Q846 Q846 Q849 Q849

The Q845 and Q846 ET Power Supplies utilize our patented qBoost technology specifically for 3G/4G/LTE applications in smart phones and tablets.

The Q849 ET Power Supply also uses qBoost, but with enhancements specifically for WLAN applications, including extremely low power wearable products.

The qBoost architecture guarantees Q845, Q846 and Q849 provide leading performance with all types of PAs including:

  • APT PAs and ET PAs (including high load line versions)
  • Single band PAs, Multi-band PAs, PA modules, and PA/Duplexer modules
  • The latest generation of CMOS PAs

qBoostTM Ultra-Fast Power Supply Technology

qBoost combines digital and analog power supplies in one chip through a unique frequency combining network to achieve a power supply that offers the best of both worlds; the high efficiency of a conventional switching power supply, and the speed and low noise characteristics of a linear power supply.

Using this patented combination of switching and linear supplies provides a unique and highly effective envelope tracking power supply that continuously adjusts the PA voltage to maximize PA efficiency and increase peak RF output power.
