Microstrip doubler microwave with non-traditional implementation
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2019 Frequency multipliers are used in electronic devices to generate spectrally pure sinusoidal signals in the frequency range from a few to tens of GHz. The multipliers are used to multiply the frequency of highly stable but more low-frequency devices with ...

Low jitter frequency multiplier [PDF]
, 2019 182 p. This thesis I explore the research in the area of low jitter frequency multipliers before proposing a novel new design for such a multiplier. The thesis begins with an analysis of the random and deterministic noise arising from conventional phaselocked loop (PLL) and delay-locked loop (DLL) based frequency multipliers.

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Advanced Engineering Materials, EarlyView.The effect of temperature controllers that are commonly used in freeze‐casting is investigated in this work. Temperature controllers are observed to generate a voltage in the slurry. Microstructural alignment and ultimate compressive strength data show this voltage to interfere with the ability to align the microstructure using magnetic fields ...

High-performance aperiodic frequency multiplying
Electronics Letters, 1979 A circuit is described that multiplies the frequency of a sinusoidal signal by a factor of 3 (and even of 5) yet maintains the input/output amplitude ratio strictly constant over a large range. A special translinear configuration was designed and used, together with commercially available analogue multipliers, to build the circuit.
