Power MOSFETs Boost Efficiency In Handheld Products July 07, 2008
Operating in a two-stage amplifier, the RQA0010 and RQA0014 power MOSFETs allegedly achieve the industry's highest level of performance: a 1.2W output at 3.6V. The transistors are suitable for use in the transmitter power amplifiers found in handheld wireless products including those that combine communication, information, and multimedia capabilities. They also lay claim to delivering the industry's highest efficiency class and the high reliability characterized by a rating of ESD immunity level 41. A unique fabrication process enables a 60% power-added efficiency (PAE) in the RQA0010 at 3.6V and a 55% PAE in the RQA0014 at the same supply voltage. Additionally, both devices come in UPAK packages measuring 4.5 mm x 2.5 mm x 1.5 mm. Available this quarter, sample prices for the RQA0010 and RQA0014 are $0.30 and $0.19 each, respectively.
