Description
WPI is introducing this new ceramic BALUN transformer specifically
designed for 2.45GHz ISM Band application, as show in Fig 1. This
BALUN is applicable for Wireless LAN IEE802.11b and Bluetooth
TM
typically located on this unlicensed frequency band which range covers
from 2.4GHz to 2.4835GHz. To fulfill 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 low 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 very small dimensions
(2.00 x 1.25 x 0.95mm
3) which meet the SMT automation and
miniaturization requirements on modern portable devices.
Marking
There is no marking. The white block means right side up and
unbalanced input.
