Transformer Types at a Glance
Matching Transformers (JT Series)
When your system has a known load impedance, a matching transformer offers a straightforward and highly efficient way to optimize RF power transfer. E&I's JT Series transformers are designed to minimize reflected power, improve amplifier efficiency, and protect both the amplifier and load by ensuring proper voltage and current levels. These transformers are especially effective in applications like high-intensity focused ultrasound (HIFU), where consistent power delivery to a fixed load is essential for reproducible results.

Compact and passive, they're meant to be positioned close to the load—minimizing cable losses and reducing the effects of distributed capacitance. With broad impedance coverage and precision-wound construction, JT Series transformers support seamless system integration across a variety of lab and test setups.

Impedance range: 3 Ω to 800 Ω
Frequency band: 10 kHz - 10 MHz
Power rating: 150 W, with custom high-power variants available
Designed for low-loss performance and close-proximity placement to the load
