TDK's high-attenuation band pass filter for 2.4 GHz WLAN and bluetooth

TDK Corporation announced that it has developed a multi-layer band-pass filter for 2.4 GHz wireless LAN and bluetooth applications that achieves the same low-loss and high-attenuation characteristics of earlier products.

The new filter design uses a compact resonator and a low-loss structure for the resonator connector to achieve a low-loss, high-attenuation filter in a 1608-size component resulting in 40% less volume.

The mobile phones have been made smaller and lighter while functioning at higher speeds and higher frequencies. The advanced features of this newly developed filter helps to equip such devices with short-range wireless communications systems such as wireless LAN and bluetooth with high-speed, high-volume data communications.

Some of the features are:

1. Ideally suited for use in handsets, modules and applications where WLAN and bluetooth systems will be co-located near cellular radios.
2. The filter provides the required attenuation needed to reduce the cellular signals from interfering with the WLAN and Bluetooth radios.

Availability: Samples are available to qualified customers.
Production for the new filter began in September
