High-Performance Wideband GaN Power Amplifier for Electronic Warfare Applications

Qorvo has introduced a high-performance wideband power amplifier (PA) for electronic warfare, radar and test instrumentation applications. The TGA2962 breaks through multiple performance barriers with an industry-leading 10 Watts of RF power from 2 to 20 GHz with 13 dB of large-signal gain, and 20-35% power-added efficiency. This combination delivers the flexibility that system designers need to improve system performance and reliability while reducing component count, footprint and cost.

Qorvo has taken a significant step forward in the wideband space with the TGA2962, enhancing not just frequency range but every other performance aspect. The company claims that no other company offers a single PA with this output power, bandwidth, power-added-efficiency, and large-signal gain. The TGA2962 is built on Qorvo’s highly reliable Gallium Nitride (GaN) QGaN15 process technology, enabling its industry-leading capabilities. In addition, improved component integration – and use of a smaller driver amp enabled by the 13 dB large-signal gain – resulting in a smaller device, making this a compelling solution for programs that require size, weight, power and cost (SWAP-C) improvements.

The TGA2962 is available as a die to customers now:
Frequency2 to 20 GHz
PSAT(PIN = 27 dBm)10 to 15 W
PAE (PIN = 27 dBm)20-35%
Large Signal Gain13 dB
Small Signal Gain20 dB
Bias22V/1.68A
Die Dimensions3.24x3.24 mm die package

The defense market, primarily radar and communications applications, is seeing strong growth from new systems and major platform upgrades. This is also providing fuel for the GaN growth engine and should bode well for companies like Qorvo. Qorvo offers the industry’s largest, most innovative GaN-on-SiC portfolio to help customers realize significant improvements in efficiency and operational bandwidth. The company’s products deliver high power density, reduced size, excellent gain, high reliability, and process maturity, with volume production dating back to 2000.
