| Abstract: | In this paper,a LTCC(low temperature co-fired ceramic) chip multiplayer coupler is presented.The operation features two coupled multiplayer inductor with higher negative coupling coefficients.The operation frequency of the coupler is 400～520 MH.Its size is only 1.6 mm×3.2 mm×0.76 mm when implemented by a standard LTCC technology.Its coupling is-20±2 dB,the isolation is-35 dB typically and the return loss is less than-20 dB. |
