Første 50V MMIC'er til S-band radarapplikationer

Wolfspeed har introduceret to nye GaN MMIC'er, og der er tale om de første 50V GaN devices, der er specielt designet til S-band radar (2,7-3.5GHz) applikationer (in english).

Dette er en prøve. Wolfspeed, a global leader in wide bandgap semiconductor technology and provider of of the industry's most field-tested SiC power and GaN-on-SiC RF solutions, has introduced two new GaN MMICs, the first 50V GaN devices specifically designed for S-band radar (2.7-3.5GHz) applications.

These new 50V GaN MMICs enable radar systems designers to reduce time to market with a less costly, less complex, 50V power amplifier line-up, while delivering the most efficiency possible.

With a best-in-class combination of power, gain, and efficiency in low-cost plastic packaging, these new MMICs, available in 15W and 30W options, can operate as drivers for higher-voltage HEMT devices used in the output stage for S-band civil and military pulsed-radar amplifiers, or as output stage devices for S-band phased-array radar applications.

- Wolfspeed will demonstrate the industry's first 50V MMICs for S-band radar systems, our 15W/50V and 30W/50V S-band MMICs, at the 2017 International Microwave Symposium (IMS), says Jim Milligan, RF and microwave director, Wolfspeed.

- 50-volt operation offers many advantages over 28-volt operation. In addition to enabling wider bandwidth performance from the simplified impedance matching, the higher voltage results in lower current and therefore lower I 2R losses in power distribution systems. The higher voltage also generates a higher RF power density resulting in a physically smaller MMIC for a given RF output power, which supports smaller, lighter weight radar systems.

The new MMICs complement Wolfspeed's previously released high performance CGHV35150 and CGH31500/CGH35400 output stage devices by operating as driver stages for these 150W and 400W devices, or as output stage devices for phased array radar applications covering full S-band applications at 2.7-3.5GHz.
