5G Multi-carrier DAS

GDM 3436-MC

The GDM 3436-MC product is a 5G-dedicated DAS system developed to cover 3.5GHz frequency band coverage.

The DAS can support up to four operators based on each operator’s 4T4R input, and the SU is designed to cover two output power specification: HSU (High-power SU) and LSU (Low-power SU), so that the coverage can be flexibly conducted for the installation purposes.

By applying ultra-broadband DPD technology, the service bandwidth of SU has been extended to 280 MHz, and it also can be designed as a single SU up to 300 MHz band depending on the market needs.
