Cree® Releases Higher Power + Efficiency + Creates Breakthrough Ku-Band MMIC HPA

[SatNews] Cree, Inc., a supplier of GaN-on-SiC high electron mobility transistors (HEMTs) and monolithic microwave integrated circuits (MMICs), has released the highest power Ku-Band MMIC available. Covering the 13.5 -14.75GHz commercial satcom band, the new 30W GaN MMIC two-stage high power amplifier (HPA) enables the satcom industry to achieve higher power, more efficient Ku-Band solutions than the incumbent TWT or GaAs solutions utilized today.

Available in a compact (25mm x 9.6mm), 10-lead, metal/ceramic flanged package CMPA1D1E025F, or as a bare die CMPA1D1E030D, the 50Ω Ku-Band MMIC HPA operates at 40V VDD, and delivers satcom measured performance of 20dB linear gain at 42dBm average output power, while maintaining linearity under the -33dBc OQPSK signal, and with adjacent channel power at a drain efficiency of 20 percent. The new 30W GaN MMIC HPA also delivers higher breakdown voltage, power density, and thermal conductivity than comparable Si, GaAs, or GaN-on-Si transistors, in addition to wider bandwidth performance.

“Cree’s new Ku-Band GaN MMIC HPA was specifically designed in response to customer requests for higher power and higher efficiency Ku-Band amplifier solutions. Delivering higher power, gain, and efficiency at an affordable price point, this amplifier will set the new standard for Ku-Band performance,” said Tom Dekker, director of sales and marketing, Cree RF.

The new 30W Ku-Band GaN MMIC will be one of the many Cree® products on display at the 2015 International Microwave Symposium (IMS), which will take place May 17–21 in Phoenix, Arizona, and will be stocked at Digi-Key and Mouser by mid-summer 2015.
