Multilayer LTCC ( Low Temperature Cofired Ceramics ) Technology Reflow solderable Miniatured Size 3.2 x 2.5 x 1.5 mm3 Low Insertion Loss High attenuation on 2nd harmonic suppressed Suitable for 2.45 GHz Working Frequency Operation APPLICATIONS 1. 2.4GHz ISM Band RF Application 2. Bluetooth, Wireless LAN, HomeRF CONSTRUCTION Fig 1. Outline of 2.4GHz Band Pass Filter DESCRIPTION Walsin Technology Corporation develops a new ceramic Band Pass Filter specified for 2.4 GHz ISM Band application, as shown in fig-1. Both of Wireless LAN IEEE 802.11b, and Bluetooth TM typically located on this unlicensed frequency band which range covers from 2.4GHz to 2.4835GHz. To fulfil the in-band and out-band frequency requirements, this Band Pass Filter has been designed to a high suppression on 2 nd harmonic as well as low insertion loss characteristics through Walsin's advanced LTCC (Low Temperature Co-fired Ceramic) technology and superior product design via 3D EM Simulation Skill. This Band Pass Filter has a rectangular ceramic body with a tiny dimension of 3.2 x 2.5 x 1.5 mm3 future meet the SMT automation and miniaturization requirements on modern portable devices.
