Standardizing Space Ovenized Crystal Oscillators for Lower Cost and Faster Delivery

Building for space is challenging. Program management requirements, parts availability and delivery, parts costs, and testing costs historically make space OCXOs expensive and longlead. Standardizing specifications based on MIL-PRF-55310, NASA EEE-INST-002, NASA Parts Selection List, and GSFC Preferred Parts Lists, and procuring parts to vendors standard drawings can significantly reduce costs and improve delivery of high-performance OCXOs.

Over-the-Air Pattern Measurements for a 32-Element Hybrid Beamforming Phased Array

In this paper we summarize measured receive antenna performance for a commercially available 32-element phased array demonstrator. The demonstrator is configured for hybrid beamforming with eight elements per subarray and four digital channels. The test setup and calibration steps are explained sequentially along with the measured calibration accuracy achieved. Three-dimensional radiation patterns of the antenna array are shown for various electronically steered beam positions including amplitude tapering.

Practical Considerations in the Design and Development of High Frequency Power Splitters

Recent trends and developments, such as 5G deployment, massive MIMO and beamforming, automotive radar, and space applications, are shaping the field of RF communications of the 21st century, particularly in the context of millimeter waves. In this article, the concept of a conventional surface mount planar Wilkinson power splitter is revisited and examined at frequencies above 20 GHz.
