BLF188XR

Newest member of popular XR family of RF power transistors for the toughest engineering environment.

NXP Semiconductors N.V. (NASDAQ:NXPI) today introduced the BLF188XR – the newest member of its XR family of “eXtremely Rugged” LDMOS RF power transistors. Designed for the toughest engineering environments, the BLF188XR delivers improved ruggedness in real-world conditions, capable of withstanding a severe load mismatch with VSWR greater than 65:1 at 5 dB of compression. The BLF188XR is capable of providing an outstanding 1600 W of peak output power and can operate as high as 60 V, and still pass extreme ruggedness testing. Other key features include stronger integrated ESD protection allowing the BLF188XR to be used in a Class C mode of operation, and several enhancements that make the XR device easy to design in and tune in multiple applications.

Another interesting feature of the BLF188XR is its excellent linearity, making it a very interesting candidate for high-power linear applications. The BLF188XR is ideal for large-scale industrial, scientific and medical (ISM) applications in frequency ranges under 300 MHz, while the popular BLF578XR series is recommended for frequency ranges up to 500 MHz. NXP is showcasing the BLF188XR this week at the IEEE MTT-S International Microwave Symposium (IMS 2013), and a video of the live demo is available here: http://youtu.be/OSp54qHiS5E

Features and benefits:

  • eXtremely Rugged high power delivery up to 1400 W
