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