LanJian

LanJian (兰剑), formally Zhenjiang Lanjian Electronics Co., Ltd. (镇江蓝箭电子有限公司), is a Chinese manufacturer of radio-frequency (RF) coaxial interconnect products. Its official website presents a broad catalogue organised around several core product families: RF coaxial connectors, RF adapters, cable assemblies, high-speed multi-channel connectors, cables, terminations/loads, attenuators, and tools and accessories. The company operates a bilingual (Chinese/English) e-commerce-style site with product search, a shopping cart and a support centre, indicating that it sells both domestically and to overseas customers. The connector range is unusually wide for a specialist of this kind. It spans legacy and general-purpose interfaces such as BNC, TNC, Type N, SMA/SMAA, SSMA, SMB, SMC, MCX, MMCX, 7/16 and 4.3-10, alongside precision millimetre-wave series including 1.0 mm, 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, 3.5 mm and 7 mm. The catalogue also covers SMP, SMPM, SMPS, SBMA, BMA, NMD, HV/SHV, L8, L9, C4, SC, L10, PM10 and other specialised interfaces. This mix positions LanJian as a supplier to RF, microwave and test-and-measurement markets rather than a consumer-facing brand. Adapters (射频转接器) are a prominent part of the offering, including in-series and between-series types. Product pages give detailed technical specifications such as connector series, port gender, body style, shell material (for example stainless steel), mounting method, polarity, impedance (typically 50 ohm) and maximum frequency. One documented example, the 2.92-KKF-278, is a 2.92 mm female-to-female in-series adapter rated to 40 GHz; another, the 2.92/SMPS-JJ, is a 2.92 mm male to SMPS male adapter also rated to 40 GHz. The site also lists very high frequency parts such as a 1.0 mm male-to-male adapter rated to 110 GHz and a 1.0 mm male to SMPM female adapter rated to 65 GHz. Beyond connectors and adapters, LanJian supplies cable assemblies built on flexible and semi-rigid cable, high-speed multi-channel connector systems (HSMC-SMPM and HSMC-SMPS), terminations/loads, attenuators, and tooling such as interface gauges and wrenches. The company's registered website carries a Jiangsu ICP filing (苏ICP备09024554号-1) and publishes service hotlines and a WeChat service account, consistent with a Chinese industrial supplier serving engineers and procurement teams. Because the available evidence comes from the company's own website, details such as founding year, ownership structure and financial status are not documented here. What is clear is that LanJian is an active, specialised RF interconnect brand whose product depth — from common coaxial connectors to 110 GHz precision adapters — places it in the microwave and millimetre-wave component supply chain.

The available evidence for LanJian comes from the company's own website and does not document its founding date, corporate history or ownership. What can be established is the shape of the business as it presents itself today. Zhenjiang Lanjian Electronics Co., Ltd. (镇江蓝箭电子有限公司) operates from Zhenjiang in Jiangsu Province, China, and runs a bilingual Chinese/English website at lanjian.com.cn. The site is structured as an online catalogue and storefront: it offers login and free registration, a shopping cart and checkout, a support centre, a brand zone, news and events, careers and contact pages. The footer carries a Jiangsu ICP filing number (苏ICP备09024554号-1) and service hotlines, and the company also promotes a WeChat service account. This combination of features is typical of a Chinese industrial component supplier that sells both directly to domestic customers and to overseas buyers through an English-language interface. The product architecture is organised into clearly labelled families. The largest is RF coaxial connectors, subdivided by interface standard: SMA/SMAA, SSMA, Type N, TNC/TNCA, 4.3-10, 7/16, SMPS, SMPM, SMP, SBMA, BMA, BNC, SC, L10, PM10, HV, SHV, L8, L9, C4, SMB, NMD, and precision series from 0.8 mm and 0.6 mm up through 1.0 mm, 1.35 mm, 1.85 mm, 2.4 mm, 2.92 mm, 3.5 mm and 7 mm. A parallel family covers RF adapters (射频转接器) across the same interface standards, enabling both in-series and between-series connections. Further families include cable assemblies built on flexible and semi-rigid cable, high-speed multi-channel connectors (HSMC-SMPM and HSMC-SMPS), cables, terminations/loads, attenuators, and tools and accessories such as interface gauges and wrenches. Product detail pages expose engineering specifications. For example, the 2.92-KKF-278 adapter is described as an in-series adapter with 2.92 mm connectors on both ends, a pin/socket port configuration, straight body style, stainless-steel housing, standard mounting, standard polarity, 50 ohm impedance and a maximum frequency of 40 GHz. The 2.92/SMPS-JJ adapter is a between-series part with a 2.92 mm connector and an SMPS connector, both male, straight, stainless steel, standard mounting and polarity, 50 ohm impedance and 40 GHz maximum frequency. The site's recommended-products section also highlights a 1.0 mm male-to-male adapter rated to 110 GHz and a 1.0 mm male to SMPM female adapter rated to 65 GHz, indicating capability in the highest-frequency coaxial interfaces. Because the evidence is limited to the company's own web presence, this dossier does not assert founding year, founders, parent company, ownership, listing status or financial data. The brand should be understood as an active, catalogue-driven RF interconnect supplier whose breadth runs from common 50-ohm coaxial connectors to precision millimetre-wave components.
