A new vertical transition using a trough line, a slab line and shielded multilayer coplanar waveguides (SMCPW) was proposed in order to develop a DC to 50 GHz band low loss LTCC hermetic surface mounting (SMT) MMIC package. The trough line, the slab line and the SMCPWs were employed to minimize the radiation loss, crosstalk and discontinuity of the conventional via vertical transition. The proposed vertical transition was made with the multiple transmission lines that consist of the SMCPW1 - trough line - slab line - SMCPW2 - SMCPW3. The manufactured LTCC hermetic SMT MMIC package showed the low insertion loss less than 0.6 dB and the reflection loss below -20 dB in the frequency range from DC to 53 GHz. © 2007 EuMA.
