With the rapid iteration and large-scale popularization of 5G communication technology, terminal devices are imposing ever-rising performance requirements for transmission rate, response latency and connection capacity, which directly drives the upgrading of quartz crystal oscillators—core electronic components—toward higher frequency and miniaturization, fueling an explosive growth in market demand for high fundamental frequency crystal oscillators.
Tracing the development of mobile communication technology, each generational leap from 2G and 3G to 4G has been accompanied by performance upgrades of quartz frequency components, with core demands focusing on frequency enhancement and stability optimization. In the 2G and 3G eras, terminal products generally adopted crystal oscillators with a 3225 package (3.2×2.5mm) and a frequency of 24MHz, which could meet the needs of basic voice calls and low-speed data transmission. Entering the 4G era, the dramatic increase in data transmission rate led to an upgrade of crystal oscillator frequency to 48MHz, with the 3225 package remaining the mainstream to match the performance requirements of mid-range communication devices.
The full-scale implementation of 5G technology has put forward more stringent technical requirements for crystal oscillators. They not only need a higher oscillation frequency to support ultra-high-speed data transmission, but also a miniaturized package to adapt to the slim and lightweight design of terminal devices, while featuring high stability and low power consumption in extreme environments. Against this backdrop, the specifications and frequency points of crystal oscillators have achieved leaping upgrades: high fundamental frequency crystal oscillators with a 1612 package (1.6×1.2mm) have become the mainstream choice in the market. Covering high frequency bands such as 52MHz, 76.8MHz and 96MHz, these oscillators perfectly meet the operational needs of core devices including 5G base stations, smartphones, IoT terminals and industrial modules with their compact size, precise frequency control and excellent anti-interference capability, ensuring the stability and high efficiency of communication links.
The technological evolution from 2G to 5G clearly demonstrates a rigid upward trend in the frequency demand for crystal oscillators, with high fundamental frequency, miniaturization and high precision emerging as the core development directions of the industry. As the "frequency heart" of communication devices, high fundamental frequency crystal oscillators will see a steady growth in market demand along with the continuous expansion of the 5G ecosystem.
