Avago’s new active bypass power amplifier dramatically improves low-power power efficiency

The acpm-7353 is the industry's first to support high, medium and active bypass power modes with low static power consumption in the industry. These unique features reduce the average current used by cdma transmitters and save power. At the same time, the acpm-7353 also supports c el lular and uspcs dual-band, and provides a simplified power design with a single RF input port per band.

Mobile phone technology The use time of mobile phone batteries is greatly related to the power consumption of power amplifiers. When the coverage of mobile networks is getting higher and higher, mobile phones often send signals at lower power, so the efficiency performance at this power level. It's important to be able to achieve optimal performance, and the amplifiers in the phone don't need to continue to work with high power output.

In active bypass mode, the accm-7353 consumes only ultra-low quiescent current as low as 3ma at 10db gain, while achieving an output power level of 11dbm, improving the low-power power efficiency of the transmitter, and the avagocoolpam technology is unique. And the innovative switch-free architecture is the basis for high power efficiency in power amplifiers, delivering up to 10% more battery life than the previous generation.

In addition to the acpm-7353, avago has introduced three other power amplifier products with active bypass mode, including acpm-7351 with iMT2000 and cellular dual-band support, acpm-7822 with j-cdma support, and cdmacellular support. The communication network's acpm-7824, these new power amplifiers are available in two sizes, with the dual-band acpm-7353 and acpm-7351 available in compact 4×5mm modules, and the acpm-7822 and acpm-7824 in miniaturized 4× Available in 4mm modules, each new simplified and integrated design based on the coolpam technology power amplifier takes up less board technology board space than a combination of two discrete power amplifiers.

 Gigabit Ethernet Media Converter adopts switching technology to fulfill media conversion. It complies with IEEE802.3, IEEE802.3u, IEEE802.3z and IEEE802.3ab standards.
