Freescale Semiconductor has introduced a wideband GaN transistor that delivers 125 watts of continuous wave (CW) power with excellent thermal performance. By offering extended operational bandwidth, the new MMRF5014H is ideal for wideband amplifiers in scientific equipment, as well as in military communications products for the U.S. defense sector including jammers, radar implementations and electronic warfare systems.
The transistor provides 100 W CW power over the 200 to 2500 MHz bandwidth with greater than 12 dB gain across the band (demonstrated on the available reference circuit). The transistor is designed to deliver 58% efficiency and easily achieves power levels in excess of 125 W in narrower band applications. In addition, to the power level the device delivers best-in-class thermal performance of less than 1° C/W and offers extreme VSWR ruggedness of 20:1.
This is the first GaN Product of many that Freescale plans to introduce to help customers push the current boundaries of performance while addressing the stringent size, weight and power (SWaP) requirements of the defense industry and other markets. “Radios today typically require multiple RF amplifiers to cover a wide frequency spectrum, but with the new MMRF5014H, only one is needed,” said Paul Hart, senior vice president and general manager of Freescale’s RF group. “Size, weight and power upgrades are critical for our customers, and by replacing several amplifiers with a single device, the MMRF5014H helps across all three of these factors.”
The MMRF5014H is included in Freescale’s Product Longevity Program, as are other RF products in the military portfolio. This transistor and all other Freescale military products are supported by a dedicated team of experts to assist customers through all stages of device selection, implementation and system development.
