Qorvo shows new GaN Power Amplifiers for Satellite Comms
Qorvo has announced a family of GaN power amplifiers that it says greatly improve the efficiency, gain and power performance of commercial VSAT and military satellite communications.
"Qorvo's high-performance GaN solutions are providing our customers with next-generation performance needed to meet their evolving system requirements," said Roger Hall, Qorvo's general manager of defence and aerospace products. "This latest family of GaN power amplifiers targeting Ku- and Ka-band satellite communications offers the highest combination of output power, gain and efficiency in the market today."
The TGA 2239-CP Ku-band PA is a 28V device with an output power of 50W. It has 30dB linear gain and 34 percent power-added efficiency (PAE).
For the Ka-band, the TGA2594-HM offers 4W of saturated output power and 25db linear gain in a hermetic, QFN package. The TGA2595-CP offers 8W of saturated output power and 21dB linear gain in a thermally superior Cu-base bolt-down package. Power-added efficiency for both parts are 25 percent and 22 percent respectively.
All three amplifiers are made from Qorvo's production-released QGaN15 process technology.
Qorvo is showing these and other GaN and GaAs products at the IEEE International Microwave Symposium (IMS) this week in Phoenix, Arizona.
