Tokyo Hy-Power Labs., Inc was founded in 1975, with intention to develop and manufacture high-quality linear amplifiers and antenna tuners for Amateur Radio Stations.

One of our early products HL-4000 linear power amplifier using 8877/3CX1500A7 by EIMAC, was the first real HF band high-power linear of its kind in Japan and was welcomed by many enthusiastic DX'ers. As HF mobile operation became popular, we became a pioneer manufacturer of full-transistorized wide-band linears for mobile use, with models HL-200B and HL-400B being a great hit. Since then, we have continued research and development for broad-band high power amps, so that solid-state RF power technology has become our main advantage in the industry.
Our RF technology developed and acquired during early stage of our history has been applied to RF power products for the industrial field, and to our super-efficient, compact 13.56MHz RF power generators as supplied for semiconductor manufacturing and plasma research facilities, as well as to other industrial and medical use products such as pulse high power and ultra wide band amplifiers.

With our long accumulated experiences and know-how in the RF field, accompanied by our constant pursuit for high quality, Tokyo Hy-Power will continue to serve the industry with advanced RF technology.
