Caiqin technology Co., Ltd (Hong Kong Caiqin Electronics Elements Co., Ltd) is a high-tech enterprise specialized in manufacturing microwave electronics ceramic products, which is mainly engaged in R&D, manufacturing and sales of the active and passive components such as microwave filter, duplexer, antenna, etc.
Thousands of products in series have been designed and produced, they are dielectric filter, dielectric duplexer/multiplexer, dielectric asymmetric splitter, dielectric coupler, dielectric resonator (TEM mode, TE01δmode, TM mode), LC filter (High pass, low pass, pass band, stop band), dielectric patch and active antenna (GPS, Beidou, Glonass, etc.), piezo ceramic filter/resonator. We are the only local Chinese manufacturer of the TE01δ and TM mode resonator and have been highly recognized by several mobile telecommunications giants.
The products cover the frequency from DC to 20GHz and widely used in the wireless telecommunications field like base station, repeater, TD/LTE RRU module, RF circuit, satellite positioning and navigation, as well as the in the aerospace and military field like radar, electronic warfare, TR selected frequency components, etc. Instead of the imported similar products, they are equipped with some well-known enterprises in the industry, large-scale units and the national key projects. Besides the domestic market, the products are exported to Europe, U.S. and Southeast Asia too.
