Today, electronic warfare applications need to detect a wide variety of signals ranging from UHF communications to GPS and other data signals in the L band to high-frequency radar signals that can fall in the X, S, or K bands. Therefore, these receivers need to operate across an extremely wide range of bandwidths to pick up and understand signals anywhere from 300MHz to 20GHz and beyond. However, a basic general wideband antenna isn’t sufficient for these applications because selectivity is needed to determine what you are actually listening to. Additionally, as if the task of designing an ultra-wideband receiver with selectivity wasn’t challenging enough, RF designers are simultaneously facing pressure to reduce the size, weight, and power (SWaP) of these applications as well.

The Future of Satellite Communication Design: Four RF Technology Trends You Need to Know
Over the last four decades, the number of devices that need to maintain mission-critical satellite communications (satcom) has rapidly grown. At the same time, the information transmitted on these devices has become increasingly more complex. As a result, the RF circuit building blocks that make up satcom technology have been through many changes to accommodate the latest advancements in the industry including miniaturization, increased reliability, and the ability to rapidly transmit more complex data.
Let’s explore the following four RF design trends we’ve identified based on our 40-years of expertise in the RF industry that are helping satcom design engineers meet the demands of the many industries relying on their devices today.
