【 摘 要 】

References(6)Cited-By(1)We propose a triplexer in a low temperature co-fired ceramic substrate for ultra-wideband (UWB) and 2.4GHz wireless systems. This triplexer can be applied to the band of 2.4GHz wireless systems (2.4 - 2.5GHz), the band group 1 (3.168 - 4.752GHz) of multiband orthogonal frequency-division multiplexing UWB wireless systems, and the band groups 3 and 4 (6.336 - 9.504GHz) of the same systems. The triplexer achieves a compact size (5.3×5.3×0.384mm3). The insertion losses are less than 2.0dB and the isolation characteristics are higher than 24dB.
