Frequently Asked Questions (Q&A)
- Q1: Does this coupler support 5G Sub-6GHz frequency bands?
- A: Yes. It covers an ultra-wide range from 617MHz to 4200MHz, which fully includes the n77 and n78 5G bands, as well as LTE and Public Safety frequencies.
- Q2: What is the significance of the -161dBc PIM rating?
- A: An ultra-low PIM of -161dBc ensures that the coupler generates minimal noise when handling multiple carrier frequencies. This is essential for maintaining high data speeds and reducing interference in modern 5G DAS systems.
- Q3: Why is "Directivity" an important parameter for this product?
- A: Directivity indicates the coupler's ability to differentiate between forward and reflected signals. With ≥18dB directivity, this product ensures precise coupling of the signal path in one direction, protecting system integrity.
- Q4: Can this directional coupler be installed outdoors?
- A: Absolutely. It is IP65 rated and has a wide operating temperature range (-35°C to +65°C), making it suitable for rooftops and other outdoor environments where dust and moisture protection are required.
- Q5: How does the coupling value (dB) affect my signal distribution?
- A: Higher coupling values (e.g., 30dB) result in less insertion loss on the main line but send less power to the coupled port. Lower values (e.g., 5dB) provide more power to the coupled port but cause more loss on the main line. This 10-option range allows for precise system balancing.
