As 5G NR communication enters a period of deep coverage, the rise of 5G micro-stations is at the right time. Compared with 4G, 5G has a greater increase in frequency and bandwidth, and it also faces greater transmission loss and poorer penetration while bringing customers faster and smoother services. Operators will use the macro base station + micro base station method to achieve a lower cost and better experience 5G network architecture according to the needs of user coverage and network optimization. In the 5G era, the construction of macro base stations and micro base stations is very important. According to relevant data, at least 10 million 5G micro-stations are required during the domestic 5G construction period.

In Jiatong Semiconductor responded to the call of the country's new 5G infrastructure to empower the new 5G kinetic energy. Just completed the first RF PA chip applied to 5G microstations. The product adopts Doherty structure, taking into account high efficiency and high linearity, and has strong system stability and anti-interference ability. The product can be applied to micro base station systems using DPD (Digital Pre-Distortion). The optimized LGA5*5mm package structure is adopted.

The product covers 3.3-3.6Ghz, adopts mature GaAs HBT process, and has achieved 50 ohm input and output matching through LGA package, supports 5G Bands 22, 42, n77, and n78, and supports 100MHz high bandwidth. The main indicators are as follows:

The product has fully reached the level of foreign competitors. Infineon makes full use of the localized industrial chain resources and will continue to build RF PA chips with completely independent intellectual property rights. In the future, Infineon will launch products in other frequency bands one after another to form a series of domestic alternatives.
