It's usually the transmit side, if you can do it, that's most useful. Even cheap receiver designs can manage a 3dB NF these days, and with the best will in the world, you won't improve that by more than 2dB - and at that, depending to some extent on the band in use, you'll be limited in fact by atmospheric and solar noise coming in the antenna.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
