RF Passive 6 IN 2 OUT POI Combiner for DAS system

This indoor 19‑inch rack‑mount multi‑channel combiner supports DCS1800 and UMTS2100 bands at 50‑ohm impedance. It has ≤5.5dB insertion loss, ≥35dB inter‑band isolation, 100W power handling and 8 N‑female ports, designed for signal combining in mobile communication systems.

1.POI (POINT OF INTERFACE) is a multi-system access platform, used for multi-frequency bands, multi-signal combination, to achieve multi-network signal compatible coverage. Realize multi-system, multi-band signal transmission and reception and sub-cable transmission; meet DTV, 2G, 3G, 4G, 5G (support LTE MIMO) and other multi-standard requirements. It is used in large buildings and municipal facilities that require multiple network system access, such as large exhibition halls, subways, train stations, airports, government offices and other places, avoiding repeated investment in the construction of indoor distribution systems. It uses passive components such as multi-frequency combiners, duplexers, isolators, bridges, etc., to talk about multiple operators, and multiple system signals (including GSM/CDMA/DCS/WCDMA/TD-SCDMA/LTE, etc.) downlink combination Output: A device that receives the uplink signal and outputs it to the relevant receiver port in a split way to achieve the purpose of making full use of resources and effectively saving investment.

The emergence of POI is a good solution to the problem of multi-system combination, and it has a good effect on signal noise or interference.

2. Product features

Use advanced technology to optimize design

POI multi-band splitter and combiner have small insertion loss, large out-of-band suppression, compact structure, and high reliability;

When designing POI, considering future expansion of the system, ports can be reserved;

Optimized design without wasting power signal.

3. Scope of application

Used for indoor coverage of wireless signals, compatible with multiple frequency bands and multiple standard signals.
