RF filters customized for LTE Band 7 and Band 8 are professional communication frequency filtering components tailored for 4G LTE mobile communication systems, targeting the core frequency bands of global mainstream 4G network operation. LTE Band 7 covers the 2500MHz–2690MHz frequency range, mainly used for high-speed downlink data transmission of 4G networks, while LTE Band 8 operates in the 880MHz–960MHz low-frequency band, featuring strong signal penetration and wide coverage, responsible for basic network coverage and stable voice communication. These two frequency bands are widely deployed in global mobile communication networks, and mutual interference between frequency bands, out-of-band clutter, and harmonic interference seriously affect the communication speed and call quality of 4G terminals. The dedicated LTE Band 7/8 RF filter solves these problems through precise frequency band matching and high-precision filtering design.

This professional LTE filter adopts targeted passband design, realizing maximum signal pass rate for LTE Band 7 and Band 8 valid frequencies while achieving high attenuation suppression for adjacent interfering frequency bands, GSM clutter, and 5G out-of-band interference. Adopting advanced BAW and LTCC composite processing technology, the component has ultra-low insertion loss in the working frequency band, ensuring high-speed and stable transmission of 4G data signals, and ultra-high out-of-band rejection capability to isolate cross-band interference. It supports 50Ω standard impedance matching, perfectly compatible with 4G mobile phone radio frequency circuits, CPE wireless routers, industrial 4G modules, and vehicle 4G communication equipment. In addition, the filter has excellent temperature drift resistance, maintaining stable frequency response and filtering performance in high and low temperature environments, adapting to complex mobile terminal working scenarios.

LTE Band 7 and 8 dedicated RF filters are core supporting components for 4G full-network communication equipment. In smartphones and tablet terminals, they ensure stable reception and transmission of 4G high-speed data and voice signals, avoid network disconnection, signal jitter, and call noise caused by frequency band interference, and improve user communication experience. In industrial 4G DTU modules and wireless data transmission equipment, they guarantee stable long-distance data transmission of industrial IoT devices, supporting reliable data interaction in smart factories, smart cities, and remote monitoring scenarios. In vehicle 4G networking equipment and portable 4G CPE routers, they suppress complex electromagnetic interference in mobile environments, ensure continuous and stable network output, and realize seamless coverage of high-quality 4G network signals.
