A U-band Wilkinson type UWB power divider in LTCC technology
This paper introduces a 1:2 ultra-wideband (UWB: 41-48 GHz) Wilkinson power divider. This power divider, with microstrip, is realized on low-temperature co-fire ceramic(LTCC) substrate which has the dielectric constant of 5.7. |S<sub>11</sub>| better than 15 dB were simulated by HFSS. |S<sub>21</sub>| and |S<sub>31</sub>| less than 3.6 dB were also simulated |S<sub>22</sub>| and |S<sub>33</sub>| are better than 16dB. And |S<sub>32</sub>| are better than 22 dB by HFSS simulation result. The size of the power divider is 3.705 × 5.77 × 0.203mm<sup>3</sup>.
