DESCRIPTION
Our new ceramic Balun Transformer specified for 2.45 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 2.5GHz (2.4835GHz). To fulfil the in-band and out-band frequency requirements,
this ceramic Balun has been designed to a low Amplitude imbalance and Phase imbalance, wide bandwidth (-10dB) as
well as l ow insertion loss characteristics through our advanced LTCC (Low Temperature Co-fired Ceramic)
technology and superior product design via 3D EM Simulation Skill.
This ceramic Balun has a rectangular ceramic body with a tiny dimension of 2.00 x 1.25 x 0.95 mm
3 future meet the SMT
automation and miniaturization requirements on modern portable devices.
