TDK Product Features

TDK's high frequency components are provided in a wide range of products as RF components used in mobile devices such as smartphones and mobile phones, as well as for navigation, Bluetooth connectivity, and wireless LAN. They form the base for IoT/M2M devices belonging to the era of analysis and application of Big-Data, which is expected to grow in the future.
A fixed frequency is used for communication between wireless devices.
A directional coupler has functions to pick up a part of the output in order to constantly maintain and control the output gain of the power amplifier (PA), and to provide feedback to the PA input.
Our directional couplers using low temperature co-fired ceramics (LTCC) are available in a wide range of products with variations in frequency, shape and size, terminal structure, specification values, etc.
