MWDC E40A-Powder Description:
MWDC E40A 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 in microwave frequency circuits (mainly in the UHF and SHF bands, 300 MHz to 300 GHz, corresponding to wavelengths between 0.1 mm and 1 m of electromagnetic waves) and performs one or more functions.
It is suitable for the manufacture of various modern microwave devices, such as frequency stabilising oscillators, filters and discriminators in electronic countermeasures, navigation, communications, radar, household satellite direct-to-home receivers and mobile telephones. These devices meet the requirements for miniaturisation, integration and low cost in microwave circuits.
