Solving Military Satellite, Radar and 5G Communications Challenges with GaN-on-SiC MMIC Power Amplifiers

Developers of aerospace and defense systems need RF power amplifiers (PAs) to perform much better across both existing and emerging applications such as military 5G and satellite communication. Systems need to meet higher gain targets but not if it comes with any increases in cost and complexity, or size and weight. As systems move to higher-order modulation schemes, they also must deliver adequate linearity and efficiency in an environment that is even more susceptible to distortion than was the case with earlier schemes. Reducing board space is another critical issue that has required challenging peak-to-average power ratio (PAPR) tradeoffs

A new generation of Gallium Nitride (GaN) Monolithic Microwave Integrated Circuits (MMIC) PAs offers a solution to these challenges, which are especially difficult for bringing 5G networking to both on-battlefield and off-battlefield applications in the unused millimeter wave (mmWave) band that is not as vulnerable to high-power jamming signals.
