MWDC E22A Powder Descriptions:
MWDC E22A Powder is one of our products from the series of dielectric microwave ceramic powders. Microwave dielectric (MWDC) is a type of ceramic material that is used as a dielectric component in circuits operating in the microwave frequency band (primarily in the UHF and SHF bands, from 300 MHz to 300 GHz with wavelengths between 0.1 mm and 1 m). It performs one or more specified functions.
This material is suitable for the production of a range of microwave devices, for example frequency stabilised oscillators, filters and discriminators in electronic countermeasures, navigation, communication, radar systems, direct-to-home satellite TV receivers and mobile telephones, thereby meeting the requirements for miniaturisation, integration, high reliability and low cost in microwave circuits.
