Shenzhen Jindasignal Technology Launches Two New Products! Wideband 4×4 Hybrid coupler Hits the Market, Empowering Dense 5G-A Network Deployment

Shenzhen Jindasignal Technology Co., Ltd., a company focusing on core technology breakthroughs in RF devices, officially launched two new high-performance 4×4 Hybrid coupler products today: the 617-3800MHz wideband Hybrid coupler and the 698-4200MHz extended frequency band Hybrid coupler. With their ultra-wide frequency coverage, low intermodulation interference, and high power handling capabilities, the two products perfectly adapt to the evolution needs of 5G-A networks, providing global telecom operators with full-scenario signal distribution solutions from macro base stations to small cells, and helping enhance network capacity and transmission efficiency.

According to the latest data from the Ministry of Industry and Information Technology, as of the end of October 2025, the total number of 5G base stations in China has reached 4.758 million, a net increase of 507,000 compared with the end of last year, and the scale of 5G mobile phone users has exceeded 1.18 billion. As 5G upgrades to 5G-A, the network has entered a new stage of "multi-band collaboration and dense deployment", which puts forward higher requirements for the frequency coverage capability and performance stability of RF components. The two 4×4 Hybrid couplers launched this time are core components tailored to address this industry pain point.

Differentiated Breakthroughs of the Two Products, Covering Full-Scenario Communication Needs

Although both belong to the high-performance product line, the two Hybrid couplers form precise complementarity in frequency adaptation and application scenarios, meeting the deployment needs of different markets at home and abroad:

617-3800MHz 4×4 Hybrid coupler: Full Coverage of Domestic Mainstream Frequency Bands

This product fully covers the frequency range from 617MHz to 3800MHz, including domestic 2G/3G/4G core frequency bands and 5G Sub-6GHz main frequency bands, making it an ideal choice for operators to carry out multi-network collaborative construction. By adopting aluminum alloy material and silver plating technology, the product has achieved excellent performance indicators: Passive Intermodulation (PIM3) is stably controlled at ≤-160dBc@2×43dBm, effectively avoiding data packet loss caused by multi-band signal interference; the insertion loss is as low as 6.5dB.

In terms of structural design, the product adopts an IP65 waterproof and dustproof design, combined with passive heat dissipation technology, which can operate continuously and stably in a wide temperature environment of -35℃ to +70℃. With a power handling capacity of 200W, it fully meets the deployment requirements of complex scenarios such as macro base stations in dense urban areas and subways.

698-4200MHz 4×4 Hybrid coupler: Dual Adaptation for Overseas Markets and Future Frequency Bands

Targeting the frequency band needs of the overseas communication market and the 5G-A extended frequency band plan, this product extends the upper limit of the frequency band to 4200MHz, compatible with mainstream communication frequency bands in Europe, Southeast Asia and other regions, providing standardized adaptation solutions for multinational equipment manufacturers. The product optimizes the cavity structure through electromagnetic field simulation, maintaining excellent amplitude and phase balance across the entire frequency band, with isolation ≥20dB, which can stably support the signal distribution needs of Massive MIMO 64T64R multi-antenna systems.

Currently, the product is made of aluminum alloy, with a powder-coated surface that is scratch-resistant and salt spray resistant. It complies with RoHS environmental standards and can be directly integrated into the overseas communication equipment supply chain system.

Focusing on the 5G-A Track, Building Full-Lifecycle Value

At present, more than 330 cities in China have deployed 5G-A networks, and the downlink peak rate per user needs to exceed 5Gbps, which puts forward rigid requirements for the wideband bearing and low-loss characteristics of RF components. General Manager Zeng, R&D General Manager of Shenzhen Jindasignal Technology Co., Ltd., stated: "The two Hybrid couplers not only meet the current dense deployment needs of 5G networks, but also reserve the adaptation capacity for 5G-A extended frequency bands. By adopting green manufacturing processes, we not only respond to the global trend of green network construction, but also provide customers with full-lifecycle value of 'available now and upgradeable in the future'."

In specific applications, the two Hybrid couplers can be widely adapted to scenarios such as wireless network optimization, Base Transceiver Stations (BTS), and Distributed Antenna Systems (DAS). In the industrial Internet field, their low-latency characteristics can support real-time collaboration of industrial robots; in smart transportation scenarios, they can provide stable signal support for Vehicle-to-Everything (V2X) systems, helping the in-depth implementation of 5G-A technology in vertical industries.

Global Pre-Order Launched, Efficient Supply Chain Response

It is reported that the two new 4×4 Hybrid coupler products have completed mass production ramp-up and been simultaneously integrated into Shenzhen Jindasignal Technology Co., Ltd.'s global supply chain system. For domestic operator customers, customized interface design and 24/7 technical commissioning services can be provided; for overseas customers, the minimum delivery cycle can be shortened to 10 working days.

Starting today, the new products have officially opened the global pre-order channel. Customers can download the complete technical specification sheet through www.jindasignal.com or call +86-755-86564010 for inquiries about sample applications.
