TDK's ANT series ceramic chip antennas feature compact and low profile designs utilizing low temperature co-fired ceramic technology (LTCC). Even with their small size and thin profile, TDK antennas maintain high performance and reliability, all with the industry's smallest "keep-out" area on the PCB which enable ease of PCB design and revision at each development stage.

The products in TDK's CU series of isolators/circulators are used as RF components in signal transmitting and receiving systems at locations such as mobile telephone base stations and microwave relay stations. With a diverse variety of frequencies, bandwidths, shape dimensions, terminal structures, and special specifications, their wide lineup extends from products accommodating low power for the initial stages of high-frequency amplifiers, to products accommodating high power for their final stages.
