Flying an Agile RF Transceiver in Space

ADI’s unique commercial space flow enables satellite bus and payload builders to integrate a modern solution rapidly that meets the specific needs of the newest generation of on-orbit space vehicles. Aside from the process, we’ll explain the rationale behind having two commercial space flows on the impacts on RF and Microwave products.

Phased Array Antenna Patterns—Part 3: Sidelobes and Tapering

In Part 1, we introduced the phased array concept, beam steering, and array gain. In Part 2, we presented the concept of grating lobes and beam squint. In this section, we begin with a discussion of antenna sidelobes and the effect of tapering across an array. Tapering is simply the manipulation of the amplitude contribution of an individual element to the overall antenna response.

Phased Array Antenna Patterns—Part 2

This is the second article of our three-part series on phased array antenna patterns. In Part 1, we introduced the phased array steering concept and looked at the influencers on array gain. In Part 2, we’ll discuss grating lobes and beam squint. Grating lobes can be hard to visualize, so we’ll draw on their similarity with signal aliasing in digital converters, then use that to think of a grating lobe as a spatial alias.
