37dBm UHF Channelized Digital Repeater, Indoor/outdoor

XiangYu  Communication’s digital repeaters use FPGA and digital signal processing (DSP), which support software upgrade for frequency re-banding, multiple sub-band selective or channel selective options without expensive hardware replacement. Innovative digital filter technologies are used to offer high out of band rejection comparing to traditional analog SAW IF filter. They are user-friendly digital signal boosters that offer cost-effective and intelligent indoor and outdoor wireless coverage solution.

They are used to pick up the signal from base station through the donor antenna, linearly amplify the signal and then retransmit it to the weak or blind coverage area through the donor antenna. Mobile signals are also amplified and retransmitted to the base station by the repeater.

These digital repeaters can be used for indoor as well as outdoor to improve the coverage in the areas where base station signals are weak or unavailable, such as airports, tourist attraction areas, golf courses,

tunnels, factories, villages, hotels, convention centers, shopping malls, business buildings, parking lots etc.

DR-450 series repeaters are UHF digital repeater which support one wide band or up to eight non-contiguous narrow bands simultaneously in the UHF frequencies. The units are configurable via web browser based GUI or SNMP manager, which provides versatility and total control to the user.

•        Support one variable bandwidth filter or up to 8 non-contiguous narrow bands (channels)

•        90dB high gain and 37dBm high output power

•        Aluminum alloy housing provides IP65 protection and natural cooling system without fan

•        Light weight and compact size, flexible wall and pole mount

•        Digital filtering technology provides excellent signal selectivity and minimum time delay
