High-power RF MOSFET targets VHF applications
Introduction
The SD2933, which utilizes a double-diffused metal oxide (DMOS) semiconductor
technology, is the latest addition to STMicroelectronics’ RF Power MOSFET family. The
packaged version is shown in Figure 1. The SD2933 is a single-ended, 50 V, 300 W, gold
(Au) metallized, N-channel, vertical Power MOSFET, intended for use up to 150 MHz, with
exceptionally high gain, and enhanced thermal packaging which makes it ideal for various
applications including plasma generation, excitation and FM broadcast applications. The
unique design of this single-ended 300 W Power MOSFET, makes it the only one of its class
available on the market today.
