Advanced Power Technology Inc. (APT, Bend, OR) announced the addition of the ARF463, ARF473 and ARF520 to its family of high-voltage RF power MOSFETs. The new devices operate reliably at dc voltages up to 175V. Each device uses the same die in different RF packages.
The ARF463, in the common source TO-247 plastic package, delivers 100W of CW output power up to 100MHz. The ARF473 uses two die in the industry-standard "Gemini" ceramic-metal package for push-pull operation, and is capable of 300W output up to 200MHz. The ARF520 has a single die in the standard 0.5in SOE package and can deliver 150W CW up to 150MHz.
Applications for these devices include RF plasma generators at 13MHz, 27MHz and 40MHz; MRI at 1.5T and 3T; CO2 laser RF sources up to 81MHz; as well as broadband linear amplifiers for 1.5MHz to 60MHz. Samples and volume production quantities are available starting four weeks ARO. At quantities of 500 pieces, the unit price for the ARF463A/B is $21.53, the ARF473 is priced at $68.75 and the ARF520 is $36.25.
