Control Line Review, an RF reference on a suspiciously familiar domain

Field notes

The publication uses a section-and-reference architecture rather than a product catalog: component families lead into measurement guidance, a parameter index, and a glossary of control terms. Its homepage illustrates the approach with a 20 dB return-loss conversion to a 1.222 VSWR figure and links to primers on absorptive versus reflective switches, switching speed, attenuator behavior, and detector curves. The site also directs readers to americanmic.com for the separate manufacturer's documentation.
