MWDC E37A Powder Descriptions
MWDC E37A Powder is one of our products from the range of dielectric microwave ceramic powders. Microwave Dielectric (MWDC) is a new type of ceramic material. It is used as a dielectric in microwave frequency circuits. These circuits mainly cover UHF and SHF bands (300 MHz~300 GHz) with wavelengths ranging between 0.1 mm and 1 m. It performs one or more functions.
It is suitable for the manufacture of various modern microwave devices, such as frequency‐stabilised oscillators, filters and discriminators. These devices are employed in electronic countermeasures, navigation, communications, radar, domestic satellite direct broadcast receivers and mobile phones. They satisfy requirements for miniaturisation, integration and low cost.
