How can AI processor reduce power consumption?
“For edge technology, the key is how to optimize the required performance while minimizing power consumption.” In view of the fact that industry activities have generally turned into virtual activities during the epidemic period, I have participated in six online semiconductor conferences since the beginning of the year. One of the hot topics discussed is […]
5g era starts, RF front end demand grows rapidly
Core point 1. 5g era starts, RF front-end demand grows rapidly. With the continuous growth of global 5g commercial and Internet application demand, the global 4G / 5G penetration rate is expected to further improve in the future. From 2G / 3G to 4G / 5G, the frequency of wireless side is increased, and the […]
Localization of RF front end
As an important part of the whole communication link, RF front-end is now highly concerned by the market. At present, the RF front-end market is characterized by “Evergrande”, with the US and Japanese giants occupying more than 80% of the market share. Due to the rapid growth of market demand caused by the accelerated construction […]

What are the causes of connector failure
Discussion on the failure of connector connection Compared with the outer conductor, the inner conductor with smaller size and lower strength is more likely to cause poor contact and lead to connector failure. Most of the inner conductors of connectors adopt elastic connection, such as spring claw elastic connection, socket slotted elastic connection, bellows elastic […]
How can domestic EDA enterprises speed up domestic substitution?
As we all know, it is impossible to catch up with the gap at home and abroad in the short term. From a more pragmatic point of view, it is considered that while facing up to the gap and catering to the “domestic substitution”, it is more important for domestic EDA enterprises to put more […]
Design and application of high efficiency class F power amplifier based on GaN HEMT
1 Introduction RF power amplifier is widely used in all kinds of wireless communication transmitting equipment. With the rapid growth of mobile communication services, the requirements of low consumption, high efficiency and small size are also increasing rapidly. As we all know, RF power amplifier (PA) is one of the most power loss design modules […]
2021 or the first year of great changes in domestic RF industry
At the beginning of the new year, everything is new. Hundreds of domestic chip companies are heading for the star sea of science and technology.
