| Application Notes for SSPA
The Model SGN-X3-400 is part of our Catalog SGN series Solid State Power Amplifiers (SSPA). The SGN SSPA series is based on the GaN technology. Utilizing the GaN technology enables us to provide our customers a lower cost SSPA, with high efficiency and higher packaging, while maintaining all of the advantages of the SSPA, such as High Reliability and Power Redundancy. The application of this series of GaN based SSPA, is to fulfill various requirements of high reliable products at lower cost. Typical applications of this SSPA are for Radar, Data Links, Communications and Test Systems. Following please find the basic block diagram of the microwave section. It consists of an input section with preamplifier stages and a power amplifier output section. The output section consists of summation of 12 amplifiers. In addition to the microwave section, there is a proprietary designed asynchronous low-noise power supply and pulse-modulator. |
