Electromagnetic compatibility (EMC) and RF test labs require high-power, broadband amplifiers that maintain linearity, stability, and repeatability. This demonstration highlights how Maury Microwave state-of-the-art GaN-based solid-state power amplifiers (SSPAs) are optimized for these test environments. Users will observe key performance metrics, including output power, gain, gain flatness, spurious behavior, and linearity, as well as the advantages of GaN architectures, from wide bandwidth and high efficiency to compact size and rugged reliability.
In this test setup, the high-performance SGX1000 signal generator provides the RF signal, where a portion is sampled by the LLC directional coupler. Two RTP5000 series real-time power sensors, which connect to a PC or PMX40 power meter for benchtop use, measure input forward power and reflected power to verify drive level, linearity at the input, and proper loading. At the amplifier output, an additional RTP5000 sensor is used to measure output power, gain, and gain flatness across operation frequencies. A spectrum analyzer observes harmonics, spurs, and overall spectral behavior.
The performance displayed in this configuration demonstrates how Maury next-generation amplifiers deliver high RF power with precision and stability across a broad frequency range.
