TDK offers an extensive range of high frequency related products. The lineup includes a large selection of diplexers, antenna switch modules, baluns, and couplers to suit a wide variety of uses such as cellular phones, wireless LAN, and Bluetooth. To meet the ever increasing need for compactness, slimness, light weight, and high performance, we have been making full use of our material technologies such as ferrites and ceramics, as well as the thin-film technologies built upon years of experience. In addition to further expanding our LTCC product range, we are pressing ahead with developing new products such as SAW duplexers and an assortment of modules.
