Since 1952

The “RF Power Amplifiers Inc.”  is a division of Industrial Test Equipment Co., Inc. which was founded in 1952.

Until 1990, Industrial Test Equipment manufactured AC power supplies and power amplifiers to cover the frequency range of 10Hz to 20KHz. At that point, Industrial Test Equipment Co., Inc. decided to push the frequency up into the radio frequency range. That is why they formed the RF Power Amplifier division. After years of effort, the upper frequency limit of the power amplifiers was pushed up to 1MHz and later to 2MHz.  A single power amplifier that could cover the frequency range from 10Hz to 2MHz  did not exist before “RF Power Amplifiers Inc.” developed its latest models.

For frequencies below 1MHz, transmission lines are not necessary for the transportation of the output power from the power amplifier to the load if the load, especially in the case that the load is not too far way from the power amplifier (less than 200 feet). Hence, we equipped the output impedance of the power amplifier to be zero ohms, which can enable the highest efficiency from the power amplifier and make the load matching much easier, especially when there is a reactive load. For applications that involve transmission lines for transportation of power, our power amplifiers can be easily changed into either 50 ohms or 75 ohms, depending on the application.
