DESCRIPTION

Walsin Technology Corporation develops a new ceramic Balanced Type Band Pass Filter specified for 2.4 GHz ISM Band

application, as shown in fig-1. Both of Wireless LAN IEEE 802.11b/g/n, and Bluetooth^TMtypically 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 Balanced Type Band Pass Filter has been designed to a high suppression on 2^ndharmonic 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 Balanced Type Band Pass Filter has a rectangular ceramic body with a tiny dimension of 2.5 x 2.0 x 1.2 mm³future

meet the SMT automation and miniaturization requirements on modern portable devices.
