DESCRIPTION
Walsin Technology Corporation develops a new ceramic Low Pass Filter specified for 5GHz ISM Band application, as shown
in Fig.1. To fulfil the in-band and out-band frequency requirements, this Low Pass Filter has been designed to a high
suppression on 2
nd
and 3
rd
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 Low Pass Filter has a rectangular ceramic body with a tiny dimension of 2.0 x 1.25 x 0.9 mm
3
future meet the SMT
automation and miniaturization requirements on modern portable devices.
