UIYDC1919A3200T3400 drop in circulator is a high-performance RF component tailored for 5G applications in the 3200–3400MHz band (n78 indoor band). It delivers cost-effective solutions for operators’ indoor coverage, small-cell development and RF system integration, and satisfies the strict demands for stable signal transmission in high-density environments.
As the indoor-specialized portion of the n78 band, 3200–3400MHz is recognized as the ideal mid-band for 5G deployment. It combines strong penetration performance and high transmission speed, effectively addressing the indoor coverage limitations of macro base stations. Supported by a mature industry ecosystem, excellent terminal compatibility and sufficient bandwidth, it enables high-speed, low-latency services while reducing construction and operation costs for operators through optimized deployment density.
Benefiting from superior band characteristics and reliable performance, this circulator is widely applied in:
- 5G coverage for high-traffic venues including shopping malls, office buildings and hospitals;
- Signal enhancement in enclosed areas such as subways and underground parking lots;
- Private communication networks for industrial Internet and smart campuses;
- Integration with 5G indoor small cells and distributed antenna systems (DAS);
- Matching with RF test equipment and other microwave components.
