摘　　要：Lumped element lowpass filter(LPF)for ultra-high frequency(UHF)radio frequency(RF)front-end system is presented based on multilayer liquid crystal polymer(LCP).The lumped element LPF can achieve miniaturization and one transmission zero on the stopband by the 8-shaped inductor.The lumped element LPF is fabricated on a 4-layer LCP substrate with a compact size of 9 mm×14 mm×0.193 mm.The measured cut off frequency of the lumped element LPF is 0.5 GHz with insertion loss(IL)less than 0.37 dB.Both measured and simulated results suggest that it is a possible candidate for the application of UHF RF front-end system.
