698-3800MHz Directional Coupler for Indoor Signal Coverage 2G 3G 4G 5G Telecom Equipment

ZD-DC-738-300-05NF
This directional coupler covers a wide frequency range of 700‑3800MHz, supporting 2G,3G,4G and 5G indoor telecom signal coverage. It offers multiple coupling options including 5dB,6dB,7dB,10dB and 15dB, with stable coupling tolerance and low insertion loss. It achieves directivity ≥15dB and VSWR ≤1.3, and features ultra-low PIM performance below -150dBc at 2×+43dBm. Rated for 300W average power and 1000W peak power, it adopts N-F 50Ω connectors. Working temperature spans -25℃ to +65℃ for stable indoor operation. This low PIM coupler is widely deployed in IBS and DAS indoor distributed antenna systems for signal sampling and monitoring in cellular communication networks.
