162 CHAPTER 5 Engineered carbon nanotube ﬁeld emission devices

5.2.4 MICROWAVE SOURCES

Most long-range telecommunication systems employ microwave links requiring high

power transmitters, both terrestrial and satellite-based. These satellites are typically

equipped with 50–100 traveling wave tubes (TWTs) based on slow thermionic elec-

tron sources that cannot be switched at high speeds, and that do not satisfy a power

budget of tens of Watts. Present day TWTs are bulky and heavy. They consume valu-

able portions of a satellite’s volume/weight budget. Miniaturization would give sub-

stantial cost savings and aid the development of microsatellites. ...

Julian F.

Head of Cybersecurity

I wanted to learn C and C++, but it didn't click for me until I picked up an O'Reilly book. When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.

Addison B.

Field Engineer

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
