The monitoring of processor temperature is crucial to increase its efficiency. One the novel approaches use information not only about CPU (Central Processing Unit) thermal state, but also changing environmental conditions. additional difference sensor monitor changes in environment necessary. dedicated for active heat sink, often used inside laptops, was designed, fabricated and investigated. ...

This paper describes two photolithographic processes for patterning Low Temperature Co-Fired Ceramic (LTCC) tapes. The processes involve the use of two types of LTCC tape. In one case photoformable tape is used, and in the other, DuPont 951 tape coupled with DuPont Riston 9015, a dry photoresist, is used. Although a full 8-layer sensor was not completed using either method, single spirals wer...

We present the development, implementation and measurement of a 3D-deployed RF front-end System-onPackage (SOP) topology in a standard low-loss multi-layer ceramic (LTCC) technology. A compact 14 GHz GaAs MESFETbased satellite transmitter integrated with a low-loss embedded filter for outdoor units were built on a 400 × 310 × 35.2 mil3 943AT tapes. The LTCC stripline filter exhibits a measured ...

In this paper, a compact and broad-band integrated transition between laminated waveguide in a multilayer low-temperature co-fired ceramic (LTCC) substrate and standard air-filled rectangular waveguide is presented. A parallel inter-coupled two-pole filter equivalent circuit is employed to interpret the working mechanism of the transition and to predict the performance. A -band prototype of the...

A novel implementation and associated design formula for a compact low-temperature cofired ceramics (LTCC) lumped-element second-order bandpass filter are proposed in this paper. The filter schematic that provides two finite transmission zeros is well known. It is shown in the paper that the filter schematic is built on a pair of conventional inductive coupled resonator tanks with a feedback ca...

In the millimeter-wave bands, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high permittivity and large-loss tangent material. In this report, an air-layer is inserted in a LTCC waveguide of εr=6.6 and tanδ=0.013 to reduce the transmission loss. The reduction of the equivalent dielectric constant by the air insertion structure enhanc...

As-fired thick-film resistors have the resistance tolerance within ±20% and this tolerance is increased for smaller components. Therefore the novel trimming methods are necessary for microresistors, especially when they are embedded in LTCC substrate. This paper compares electrical (normalized temperature dependence of resistance, low frequency noise) and stability properties (relative resistan...

In this paper the MBS (Magnesium borosilicate) based glass-ceramic have been prepared and characterised to find its suitability in Low temperature cofired ceramics (LTCC) technology. The glass-ceramics were prepared by using conventional solid state route. The experimental study was conducted on the MBS glass-ceramic containing MAS (Magnesium Alumino-Silicate) based glass-ceramic as an additive...

Ca(2+) influx through postsynaptic Ca(v)1.x L-type voltage-gated channels (LTCCs) is particularly effective in activating neuronal biochemical signaling pathways that might be involved in Hebbian synaptic plasticity (i.e., long-term potentiation and depression) and learning and memory. Here, we demonstrate that Ca(v)1.2 is the functionally relevant LTCC isoform in the thalamus-amygdala pathway ...
