Qorvo Inc, a provider of core technologies and RF solutions for mobile, infrastructure and aerospace/defense applications, has launched a family of gallium nitride (GaN) power amplifiers (PAs) that are said to dramatically improve the efficiency, gain and power performance of commercial VSAT and military satellite communications.
"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," claims Roger Hall, general manager of Defense & Aerospace Products.
Already having a poer output of 35W, the TGA 2239-CP Ku-band PA (operating at 13.25-15.15GHz) will be released at 28V, elevating the output power to 50W. With what is claimed to be superior thermal management (even under CW operation), the device has 30dB linear gain and 34% power-added efficiency (PAE).
Operating at 27-31GHz in 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. The two devices have PAEs of 25% and 22%, respectively.
All three amplifiers are fabricated using Qorvo's production-released QGaN15 process technology.
Qorvo is showcasing its GaN and GaAs solutions in booth 331 at the 2015 IEEE MTT-S International Microwave Symposium (IMS) in Phoenix, Arizona (18-21 May).
