A tool to improve power levels and range

KTL-TR1 is a high-frequency transformer especially designed to improve power level and range for our high-quality resonant dipoles KTL-TRID1 & KTL-TRCD1.

Because of their very large quality factors, the KantanLabs dipoles exhibit at resonance either very low impedance for inductive dipoles or very large impedance for capacitive dipoles. These impedance values do not mach usual signal generators or amplifiers values leading to performances far from optimum.

Generator side improvements

Used in a down configuration with inductive dipole and up configuration with capacitive dipole, the KTL-TR1 will bring the input impedance around 25Ω in weak coupling situations in both cases (higher impedance values will be obtained if the coupling gets larger). These impedance values are appropriate to work in safe and well tuned conditions with either a signal generator or a power amplifier.

Load side improvements

On the load side a second KTL-TR1 will adapt the output impedance to match typical LED impedance in case of low or intermediate coupling situations. Here the KTL-TR1 adapter will be used in a down configuration when associated to a capacitive dipole and an up configuration when associated to an inductive dipole.

Overall range and power improvements

With a pair of KTL-TR1, the range for wireless power demonstrations or experiments will rise from about 30cm to about 1m. Similar improvements will be obtained for distant sensing applications such as metal or dielectric detectors. The KTL-TR1 combined to a KTL-RIDK1 kit and a 10W amplifier will also allow making simple and safe low-power induction heating experiments.
