Mobile Phone Radio Frequency Devices 0 7 “Radio Frequency Devices: The embarrassment of relying on people”s mobile phones” (Science and Technology Daily, May 7)
On a mobile phone motherboard, 1/3 of the space is radio frequency circuitry. The development trend of mobile phones is to be thinner and lighter, consume less
power, have more frequency bands, and have larger bandwidth, which poses a challenge to radio frequency chips. Radio frequency chips convert digital signals into
electromagnetic waves. 4G mobile phones must support more than a dozen frequency bands and information bandwidths of tens of megabytes. In 2018, the RF chip
market was US$15 billion; the high-end market was basically monopolized by Skyworks, Qorvo and Broadcom, with Qualcomm also occupying a place. Another key
component of RF devices – filters, the gap between domestic and foreign countries is even greater. The multi-billion-dollar market for high-end filters used in mobile
phones belongs entirely to foreign RF device giants such as Qorvo. China is the world”s largest mobile phone manufacturer, but it cannot manufacture high-end mobile
phone radio frequency components. This requires solid accumulation of materials, processes and design experience.
Heavy-Duty Gas Turbine 0 8 “”The Mingmen Fire Decline”, the Disaster of the Blades of Heavy-Duty Gas Turbine” (Science and Technology Daily, May 9)
Gas turbines are widely used in ships, trains and large power stations. Our country has the ability to automate light-duty gas turbines; however, it still
basically relies on introduction. There are four major international rekindling manufacturers: GE from the United States, Mitsubishi from Japan,
Siemens from Germany, and Ansaldo from Italy. Cooperation with China comes with stringent conditions: design technology will not be transferred,
core hot-end component manufacturing technology will not be transferred, and local manufacturing of non-core components will only be permitted
through a license. The lack of independent capabilities means that an important part of my country”s energy security is still controlled by others, and there is a risk of being “stuck.”
