- Abstract
- The new vertical transition using the trough line, the slab line, and shielded multilayer coplanar waveguides (SMCPW) in order to implement the DC ~ 50-GHz band low loss LTCC hermetic surface mounting (SMT) MMIC package was developed. The trough line, the slab line, and the SMCPWs were employed in order to minimize the discontinuity of the conventional via vertical transition, and the radiation loss and crosstalk. The proposed vertical transition is constructed using the multiple transmission lines of the SMCPWI-trough line-slab line-SMCPW2-SMCPW3. The manufactured LTCC hermetic SMT MMIC package showed a low insertion loss less than 0.6 dB and a reflection loss less than - 20 dB in the frequency range from DC to 53 GHz. © 2007 Wiley Periodicals, Inc.
