Cree and Array Wireless Score Touchdown with New GaN HEMTs

Cree, Inc., and Array Wireless, Inc., announced that Cree’s new GaN HEMT WiMAX devices now provide critical size and energy benefits to Array Wireless’ new Powerlinear power amplifiers.

Cree’s GaN HEMTs help deliver a solution that is 25% smaller and at least twice as energy efficient as competing systems. Smaller, lighter and more efficient power amplifiers are now used more successfully in certain applications, such as airborne high-definition broadcasting, as a direct result. In fact, Array’s Powerlinear amplifiers are used in blimps and in aircraft that provide TV broadcast feeds of Sunday Night Football on NBC.
“The Powerlinear amplifiers are designed to be ultra-linear and ultra-power efficient,” reports Ed Takacs, Array Wireless president. “With the new Cree GaN HEMT devices, our amplifiers use half the power of competing systems and are significantly smaller in size, both of which are critical benefits for wireless applications where space and weight are at a premium.”

The Powerlinear series is designed to work with the rigorous requirements of digital modulation formats, such as Coded OFDM. Powerlinear power amplifiers operate in a variety of bands from UHF to C and are optimized for the Nextel BAS (Broadcast Auxiliary Service) frequency relocation programs that are underway.

“Cree’s new GaN HEMT devices reduce power consumption in a variety of wireless applications. They can also significantly reduce the size and complexity of amplifiers, providing greater benefits in targeted power amplifier applications,” adds Jim Milligan, Cree product manager for wireless products.

Other targeted communications applications for the new ultra-efficient, ultra-linear Powerlinear power amplifiers include unmanned aerial vehicles, law enforcement, unmanned ground vehicles, WiMAX base stations and secure mobile military communications.
