Cree's RF GaN transistors and Array Wireless’ linear PAs deliver high-definition Sunday Night Football  

Cree Inc of Durham, NC, USA and Array Wireless are bringing high-definition (HD) video transmission to Sunday Night Football (SNF) on NBC. The HD NFL games are broadcast using wireless video systems from Array Wireless that employ Cree’s GaN RF components.

Cree GaN RF technology is deployed in Array Wireless’ S-Band linear power amplifier (PA) product series, enabling smaller, lighter and more efficient PAs than those based on gallium arsenide (GaAs), says the firm.

“Cree’s GaN RF devices are ideal for meeting the stringent linearity requirements for wide bandwidth HD digital transmission at high efficiency operation,” says Array Wireless’ president & founder Ed Takacs. “The lighter weight systems they enable are extremely beneficial in lowering fuel consumption and operating costs for our customers. We migrated from GaAs devices to Cree GaN devices several years ago to offer increased transmission range while reducing our power amplifier size, weight and power consumption.”

Array Wireless’ TruPower series linear RF amplifiers use patent-pending linearization technology to minimize distortion and provide superior signal quality for complex multi-carrier modulations like OFDM while minimizing DC power consumption, heat and weight.

Cree’s RF GaN HEMT and MMIC devices are available for linear and pulsed amplifier applications in frequency bands from DC to Ku-band at 18GHz, and are available in a variety of output power ratings from 1W to 400W.
