News on March 4, with the gradual advancement of 5G communications, new technological hotspots caused by higher frequencies have also attracted attention, and the problem of signal blindness in commercial buildings and homes is one of them. Recently, my country’s first 5G micro base station RF chip YD9601 was successfully taped out in Nanjing Yudu Communication Technology Co., Ltd., and is currently undergoing packaging testing.
It is understood that 5G base stations are divided into two types: macro base stations and micro base stations. Macro base stations are mainly used for outdoor coverage, and 5G micro base stations are mainly used indoors, with low transmit power (generally within 200 mW), and are widely used in airport high-speed rail waiting areas, commercial places, commercial buildings, schools, hospitals, park factories and community homes etc. scene.
5G micro base stations can effectively solve the capacity of indoor coverage areas (such as hotspot areas such as airports, high-speed rail and commercial fields) and coverage problems (such as commercial buildings and homes) at a lower cost.
According to reports, Wang Junfeng, a national special expert and Ph.D. from the Massachusetts Institute of Technology, said that the 5G micro base station RF chip project is an expansion of our self-developed wired RF broadband chipset.
Before the launch of the 5G micro base station radio frequency chip, Yudu Communications had a long-term accumulation of radio frequency chip technology through the research and development of the wired radio frequency broadband HiNOC2.0 chip.
It is reported that HiNOC2.0 is my country’s next-generation wired RF broadband radio and television access standard. Nanjing Yudu’s HiNOC2.0 RF/baseband chipset can achieve a downlink rate of 600 megabits per second, which is completely comparable to similar products from international giants.
In the standard test conducted by the China Academy of Broadcasting Sciences, the equipment equipped with this group of chips can still be connected under the line attenuation of 85dB. It can better adapt to the complex and harsh network environment in China.
