Beijing Sitesmart Communication Technology Co., Ltd is located in the Beijing Economic and Technological Development Zone, and specializes in the production and development of RF Connectors and feeder cable Lightning arresters (surge protectors).

We have three series of products:
RF coaxial connectors for general purpose: including connectors such as SMA, SMB SMC, BNC, TNC, N, MCX, MMCX, UHF & Mini-UHF and 7/16 DIN, which are applied extensively to the following communication connector fields as mobile communication base station cabinets, the connection between cabinets, the microwave trans mission and the indoor overlaying of mobile communication. These products feature reliable mechanicaland electric al performances, superior RF performance, robust structure and good finish by plating thickness control.

Enhanced RF coaxialconnectors: which are water proof and meet the requirements of passive itermodulation (PIM), specially applic able for the outdoor application to the antenna line of base station of mobile communication. It's excellent RF performance makes the retum loss value up to 36db (max. ), the PIM up to 160dbc and the environmental levelto IP68.

Lightning arrester series products: including product types such as common gas discharge tubes, mainly us ed as indoor type; free-maintenance outdoor type of 1/4 wavelength dual band arresters and LC broad band arresters, which are the forwarding types of the type of 1/4 wavelength arresters. Among them, LC broad band arresters are of the most advanced currently, most typically showing the features of the extensible applicability and the stability and free-maintenance of 1/4 wavelength. It makes the products applic able in a wide frequency range and secure lightning-proof and RF performances after lightning strikes of several times, free from maintainnance. In comparison to the type of 1/4 wavelength arrestore, the LC arresters present an obvious advantage, that is, it can prevent both entrance of low frequency and DC from the equipment. Furthermore, the LC arrester's typical structure also makes it poss ible to be installed without any addition grounding.

The products from Sitesmart company are produced and manufactured from the selectedraw materiale in accordance with the internationalstandards. The product defects and flaws are minimized through the strict process management, thus, the secure quality products are supplied for our customers.
