NXP Semiconductors announces a new laterally diffused metal oxide semiconductor (LDMOS) technology for RF power transistors designed for operation up to 65 V. This extra-high voltage LDMOS process will give rise to a new generation of products: the MRFX series. The first product in the MRFX series is the MRFX1K80, the industry’s most powerful continuous wave (CW) RF transistor. It is designed to deliver 1,800-W CW at 65 V for applications from 1 to 470 MHz and is capable of handling 65:1 voltage standing wave ratio (VSWR).
The MRFX1K80 is targeted for industrial, scientific and medical (ISM) applications such as laser generation, plasma etching, magnetic-resonance imaging (MRI), skin treatment and diathermy, as well as particle accelerators and other scientific applications. The MRFX1K80 is also designed for radio and very high frequency (VHF) TV broadcast transmitters. Industrial heating, welding, curing or drying machines currently using vacuum tubes will also benefit from the higher level of control that solid state enables.
The MRFX1K80H transistor in an air cavity ceramic package is currently sampling, with production expected in August 2017. Reference circuits for 27 MHz and 87.5-108 MHz applications are available now. In a few months, NXP will offer the over-molded plastic version, the MRFX1K80N, that reduces the thermal resistance by 30 percent for further reliability and ease of use.
