This paper aims to discuss the filter structures which constitutes a planar inductor, capacitors using microstrip lines and make it tunable taking the advantage of LTCC multilayer design. Investigations of passive multilayer filter structure using low-temperature co-fired ceramic (LTCC) for microwave and radio frequency application is studied. A roadmap for performance and process parameters to...

In this paper, a 60 GHz LTCC SiP with low-power CMOS OOK modulator and demodulator is presented. The 60 GHz modulator is designed in a 90-nm CMOS process. The modulator uses a current reuse technique and only consumes 14.4-mW of DC power in the on-state. The measured data rate is up to 2 Gb/s. The 60 GHz OOK demodulator is designed in a 130nm CMOS process. The demodulator consists of a gain boo...

In this work, the design and fabrication process of a stripline 90 degree hybrid coupler using LTCC technology are presented. The main specifications required for the device developed were 1.03 GHz central operation frequency, isolation higher than 23dB and a maximum size of 15 mm x 10 mm. To obtain a starting point of physical parameters for the simplified DC configuration a transmission lines...

Hasreiter J, Goldnagl L, Böhm S, Kubista H. Cav1.2 and Cav1.3 L-type calcium channels operate in a similar voltage range but show different coupling to Ca -dependent conductances in hippocampal neurons. Am J Physiol Cell Physiol 306: C1200–C1213, 2014. First published April 24, 2014; doi:10.1152/ajpcell.00329.2013.—In the central nervous system, L-type voltage-gated calcium channels (LTCCs) com...

BACKGROUND L-type calcium channel (LTCC) and Na(+)/Ca(2+) exchanger (NCX) have been implicated in repolarization-dependent arrhythmias, but also modulate calcium and contractility. Although LTCC inhibition is negative inotropic, NCX inhibition has the opposite effect. Combined block may, therefore, offer an advantage for hemodynamics and antiarrhythmic efficiency, particularly in diseased heart...

In the central nervous system, L-type voltage-gated calcium channels (LTCCs) come in two isoforms, namely Cav1.2 and Cav1.3 channels. It has been shown previously that these channels differ in biophysical properties, in subcellular localization, and in the coupling to the gene transcription machinery. In previous work on rat hippocampal neurons we have identified an excitatory cation conductanc...

To meet measurement needs in harsh environments, such as high temperature and rotating applications, a wireless passive Low Temperature Co-fired Ceramics (LTCC) temperature sensor based on ferroelectric dielectric material is presented in this paper. As a LC circuit which consists of electrically connected temperature sensitive capacitor and invariable planar spiral inductor, the sensor has its...

A novel formulation for thick-film graphite sacrificial pastes is studied in this paper. It is composed of coarse graphite powder (grain size: 25 μm), dispersed in a vehicle consisting of polyvinyl alcohol (PVA) dissolved in a propylene glycol (PG) – glycerol (G) – water mix, which is not aggressive to thin LTCC sheets. The presented sacrificial paste has been successfully applied for fabricati...

In this paper, a millimeter-wave pointto-point (PTP) Wireless Gigabit Ethernet Communication System is presented and the first been developed by TMR&D. A 60 GHz Low Temperature Co-Fired Ceramics (LTCC) SystemOn-Package (SoP) Transceiver capable of gigabit data rate has been built and demonstrated with a size of 17.76 x 17.89 mm. A direct Amplitude-Shift Keying (ASK) modulation and demodulation ...

The isoquinoline alkaloids (IAs) represent a large and diverse subfamily of phytochemicals in terms structures pharmacological activities, including ion channel inhibition. Several IAs, such as liriodenine (an oxoaporphine) curine (a bisbenzylisoquinoline (BBIQ), inhibit the L-type voltage-gated Ca2+ channels (LTCC). In this study, we aimed to search for new blockers LTCC, which are therapeutic...
