Nanjing M J K Electronic Engineering Co., Ltd. is a high-tech enterprise specializing in the research and production of microwave RF absorber materials. Our company is capable to deliver a variety of RF absorbers, including our patented Z X B absorber, foam absorber, ferrite RF absorber, honeycomb absorber, and RF absorbing sheets.
We are also technological privileged and highly experienced in design and construction of microwave anechoic chambers, near-field and far-field antenna measurement systems. In the past decades, we have produced 100,000 square meters of different kind of R F absorbers, designed and constructed 310 microwave anechoic chambers and 66 near-field and far-field antenna measurement systems. Nanjing M J K also holds 26 relevant patents and 18 self-developed operating software systems.
Our company is the biggest supplier of the patented non-flammable RF absorber (Z X B absorber inventor by Jigang Zhang) in China. The Z X B absorbers are optimized for high-temperature, high-frequency tolerate microwave anechoic chambers. Features: Good absorption ablity, non-pollutive, environmentally friendly, odorless, Long-lasting material, anti-bent tips, can withstand high power output.
Applications Fields: Antenna near and far field measurement chamber, Target R C S measurement chamber (including compact field chamber), RF simulation chamber and large E M C chamber, electromagnetic noise suppression for radar and telecom system, anti-E M I etc.
We welcome friends from all over the world to negotiate potential business collaborations.
