Freescale Semiconductor has introduced its first plastic packaged devices designed specifically for high ruggedness industrial applications. The MRFE6VP5150N/GN and MRFE6VP5300N/GN LDMOS power amplifiers are the industry’s first > 65:1 VSWR rated devices to be housed in over molded plastic packaging. They operate at a frequency range from 1.8 and 600 MHz. The MRFE6VP5150 device is capable of handling a load mismatch of > 65:1 VSWR at 50 Vdc, 230 MHz at multiple phase angles; and is capable of 150 Watts CW operation. In addition, both devices incorporate integrated stability enhancements and integrated ESD protection circuitry.
Compared to ceramic RF packages, plastic packaging features superior manufacturability, outstanding thermal impedance and significant cost benefits. By combining the advantages of plastic packaging with the ruggedness traditionally associated with ceramic-housed devices, Freescale has achieved a significant technology milestone for the benefit of its RF power customer base.
Industrial environments are notoriously harsh. Devices are required to not only survive, but perform optimally under varying voltages and operating conditions. With a survivability rating of > 65:1 VSWR with simultaneous over voltage and overdrive, the transistors are designed to thrive in these environments while delivering outstanding system reliability and low maintenance costs. Target applications for the new products include FM broadcast, CO2 lasers for medical applications, and VHF and UHF base stations for public safety radio installations.
In addition to their ruggedness, the MRFE6VP5150 and MRFE6VP5300 devices facilitate high gain across a wide frequency range, requiring fewer parts and reducing design complexity. The devices’ high energy efficiency simplifies cooling, thus lowering operating expenses and shrinking form factors.
Live demonstrations of the MRFE6VP5150 and MRFE6VP5300 devices were given at the International Microwave Symposium (IMS) 2014. Click to see what else happend at the IMS 2014.
Availability and Support
The MRFE6VP5300 is sampling now and available in production quantities. Samples of the MRFE6VP5150 are also available, and production quantities are expected in Q3 2014. A broad array of support tools, including broadband fixtures available for reference, global and regional applications support, and requisite model tools are additionally available.
