For applications requiring high linearity, exceptional gain, and superior isolation, tetrodes are the tube of choice. Trusted by engineers and system designers worldwide, tetrodes remain the dominant solution for achieving output power levels above 1 megawatt, making them indispensable in both broadcasting and industrial RF applications.
Elettroza tetrodes are widely utilized in shortwave transmitters, including those broadcasting in the Digital Radio Mondiale (DRM) format, with output power ranging from 100 kW to 1 MW. While they have long been a cornerstone in AM, FM, and television broadcasting transmitters, modern applications also extend to high-power RF heating systems, where precision frequency control is achieved using a dedicated oscillator driver.
Our tetrodes are engineered for optimal thermal performance — supporting air cooling for plate dissipation up to 40 kW, and water, vapor-phase, or multi-phase cooling for higher dissipation levels. Each unit is manufactured to stringent European quality standards, ensuring consistent performance, extended service life, and operational stability even under extreme conditions.
With one of the most comprehensive selections of power tetrodes available, Elettroza is your trusted partner for high-performance RF amplification, combining proven engineering excellence with dedicated technical support to meet your specific system requirements.
