This paper reports on research on two generic shielded vertical transitions in low-temperature cofired ceramic technology. These interconnections are simulated and optimized by three-dimensional electromagnetic simulations. The first circuit, a coplanar waveguide (CPW) or microstrip-to-stripline transition, presents great experimental performances from dc(More)
A reader module at 60 GHz for high data-rate short-range backscattering-based communications is presented. The reader consists of a CMOS-based oscillator, amplifiers, and a mixer on a low-temperature co-fired ceramic (LTCC) substrate. The filter, power splitter, and antennas are directly patterned on the LTCC. All millimeter-wave components are contained(More)
We propose a new low-temperature co-fired ceramic (LTCC) U-shaped resonator. The advantages of LTCC technology are employed to design this three-dimensional (3-D) lambda<sub>g</sub>/2 resonator. The latter is modeled and optimized by 3-D electromagnetic simulations and is validated by experimental results. In order to validate the coupling between these(More)
This paper presents an RF-MEMS SP4T switched LNA MMIC used in a 24 GHz beam-steering antenna module. The SP4T LNA has a measured gain of 10-16 dB at 16-30 GHz (NF=2.6-3.0 dB at 16-26 GHz) with up to 37 dB of isolation at 24 GHz when one of the four MEMS switches are closed while the other switches are open. To the authors' knowledge, this work represents a(More)
The concept of a via resonator is first time introduced. The advantages of the implementation of the via resonator compared to planar one are discussed. Then the different types of an interdigital filter that could be realized as via resonator filter (VRF) are considered. The perspectives to manufacture VRF with low temperature co-fired ceramics (LTCC)(More)
