PRODUCTS

Dielectric Filter components not only have advantages of low insertion loss, high rejection, and low temperature coefficient; but also, with design flexibility of customization. Due to these advantages, the Dielectric Filter components are commonly design for vehicle navigation, router, satellite TV, UAVs, wireless communication, and radar etc….
