Recently, Reactor micro held a new conference of high-efficiency power supply and released the new generation of envelope tracking (ET) chips rm6100 and rm61o2f1a1s, as well as two apt buck power chips and a buck boost power chip.

At present, the envelope tracking technology (ET) is still at the forefront in the world. The global companies that make envelope tracking (ET) power chip products include Qualcomm, Reactor micro, MTK and qorvo. Reactor micro started to develop envelope tracking technology in 2014 and obtained the patent of "a power supply for envelope tracking" for the first time in 2018. By August 2023, it had obtained 26 national invention patents related to ET and 4 international patents. Reactor micro et products have been mass-produced and have entered the commercial market, and the key indicators are better than those of foreign manufacturers such as Qualcomm. The rm61o2f1a1s newly released by Reactor micro is a commercial version customized for a UAV factory. It can support 100MHz signal broadband, and the efficiency can reach more than 80%, which is higher than the relevant efficiency index of qet7100.

The apt buck power chip released at this meeting is mainly used in mobile phones and other wireless communication devices. The buck boost power chip is used in the fields of lightning wires, optical modules and battery power supply of medical devices.

In the 5g intelligent era, envelope tracking technology (ET) has attracted much attention because it can provide dynamic power supply for RF power amplifier (PA), reduce power consumption and improve efficiency. It is believed that with the further construction of 5g network and the rapid popularization of 5g terminals, the market demand of ET in the field of wireless communication such as smart phones, watches and UAVs will be greatly driven.
