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 2nd 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.
