Coined with the low loss requirements for multiple GHz RF signals in the package, there is a critical need for dielectrics with loss tangent ~0.001 and dielectric constant close to 2.0. Thin films of 5 to 10 µm are needed to achieve high-density routing with 3- to 5-µm …
The complex permittivity of high-purity, semi-insulating, axis-aligned monocrystalline 4H-SiC has been determined over the frequency range 10–40 GHz and at temperatures from 40 up to 295 K using whispering gallery modes and quasi T E 0, n, p modes in a dielectric resonator constructed from seven layers of a 375 μm thick wafer.

In this study, we have investigated how the dielectric loss tangent and permittivity of AlN ceramics are affected by factors such as powder mixing methods, milling time, sintering temperature, and the addition of a second conductive phase. All ceramic samples were prepared by spark plasma sintering (SPS) under a pressure of 30 MPa. AlN composite ceramics sintered with 30wt%-40wt% SiC at 1600
Our recent works on silicon carbide (SiC) fiber mats-based absorbers imply that metal modifiion (e.g., Fe or Hf) could benefit their bandwidth effectively. For verifiion, we fabried a Co/SiC fiber mat via a similar electrospinning process and subsequent pyrolysis at 1400 °C in Ar atmosphere.
Materials with a high loss tangent can couple with microwaves at room temperature while less ‘lossy’ ma-terials need higher initial temperatures in order to couple. Some ﬁne powders, such as carbon , silicon carbide  and vanadium oxide  couple efﬁciently

Loss Tangent The dielectric loss tangent, or dissipation factor, is a measure of the amount of electromagnetic energy absorbed within the material and dissipated as heat. Understandably, materials with low loss tangents are desirable for high performance and high power appliions, as this would minimize the amount of loss within a transmission line or along a structure.
Low dielectric loss tangent in the high frequency band. (tanσ:10-4 at10 GHz) Ultra-thin substrates with a thickness of 0.1 mm are also available. Note: In addition to our high-grade alumina substrates we also provide ones with a purity of 99.5%.

Chemical corrosion resistance benchmark – Weight loss after 200 hours soaking in sodium hydroxide at 80 C followed by 200 hours soaking in nitric acid at 80 C The coination of high thermal conductivity, low thermal expansion, and high mechanical resistance, which makes silicon carbide meranes particularly resistant to thermal shocks (fast temperature variations).
But while this suits the tens of kHz switching frequencies demonstrated by silicon devices, hit the much higher MHz speeds of SiC systems and parasitic inductances pose a problem. Parasitic inductance in the power module induces high voltage overshoot and ringing on switching devices, which then increases the device switching loss and EMI emission from the modules.
This article presents a microwave characterization at the ISM band (2.45 GHz) for the dielectric properties of a Silicon Carbide sample with high loss tangent from 25 C to 165 C. Different techniques were used to characterize the SiC sample: the cylindrical resonant cavity technique in transmission and reflection mode, the microstrip ring resonator and finally the near field microwave microscopy.
