Keenlion, a specialized Chinese manufacturing factory of passive RF components, announces its successful involvement in a major urban transit modernization project. The company has been selected to supply custom-engineered 5.8GHz vehicular power divider and 5.8GHz vehicular combiner units for the communication systems onboard Beijing Subway Line 13 trains. that has already delivered customized 5.8GHz RF power dividers and combiners to the Beijing Metro Line 13.

Project Overview & Product Snapshot

Adhering to Strict Performance and Durability Requirements
The primary challenge involved the construction of equipment that performs consistently with physical stress. The selected 5.8GHz vehicular power divider provides the required amplitude and phase stability after exposure to train vibration. The 5.8GHz vehicular combiner provides low insertion loss together with good port isolation so that the signals across the network are retained. Dust and moisture and the great electromagnetic interference produced by train propulsion systems and other onboard electronics are shielded against both components by ruggedized shielded enclosures.

Customization from the Ground Up

Keenlion being a manufacture with a lot of engineering resources did not offer products ready to use. The project had to be completely custom. These units were being optimized by engineers at the substrate and connector level. The 5.eight GHz vehicular electricity divider turned into designed with unique output port configurations to healthy the teach's antenna layout. The 5.8GHz vehicular combiner was simultaneously designed to withstand the maximum input power and frequency stability requirements over a large operating temperature range, between cold winter and hot summer.

Ensuring System-Wide Reliability and Safety

In transportation applications, a malfunction of the component will not be acceptable. Keenlion's engineering of 5.8 GHz vehicle power dividers and 5.8 GHz vehicle combiners was followed by extensive operations to verify their reliability and redundancy. Every unit is taken under a strict check of quality before it is shipped out. These tests include sweep tests, vibration tests and thermal cycle tests. As a result, the units will provide vital communication and data services, including passenger information, operational as well as crew coordination data, and years of service without failure.

Company Advantages

For municipalities, transit authorities, and system integrators worldwide looking to upgrade or build resilient communication networks for transportation, Keenlion offers proven expertise. The company's model of direct factory customization, competitive pricing, and professional support ensures clients receive optimal solutions.
