Abstract
This paper reports on preliminary prototype development and evaluation of space-grade WDM-based HPA/LNA modules for small LEO satellite constellations. We have developed these modules to ensure reliability, tolerance for space environments, and compliance with SWaP constraints for small satellite platforms including CubeSats. These modules optically amplify WDM optical signals using up to four wavelengths. Both modules occupy less than 0.5U. The HPA module delivers an output power of over 2W, and the LNA module can amplify optical signals of -50 dBm/ch. Our evaluation confirms the fundamental performance of each module including output power, optical gain, noise figure, and gain flatness.
