Description
Designed for high-capacity network integration, this 3-way combiner utilizes a cavity or microstrip design to ensure high port-to-port isolation (typically ≥20dB to 23dB). This isolation is critical for preventing cross-talk and feedback between the three input radios. The housing is typically constructed from high-grade brass or aluminum with tri-alloy (White Bronze) plating on the connectors to ensure excellent conductivity and long-term resistance to environmental oxidation.
The device is optimized for low Passive Intermodulation (PIM), with many professional models achieving ≤ -140dBc to -150dBc. This performance is essential for maintaining a low noise floor in multi-carrier environments, which directly impacts 4G and 5G data throughput. With its broad frequency range and high power capacity, it is a versatile solution for head-end combining in office buildings, stadiums, and transportation hubs.
