I'm looking at Wi-Fi 2.4 GHz power amplifiers and I can't find a single high power (500 mW) one including a system protecting it from damage. I can, for example, find some ~ GHz PA with protection circuits, for example from Triquint (7m9106).
I burned some PAs in some of my designs over the years but in my real world experience with electronics, I don't believe I ever damaged a device by powering it on without an antenna installed.
- How are "high power" (500 mW) consumer electronics protected against users powering it on without antenna installed?
- Has the power detect output pin common in most PA anything to do with it or is it just for feedback on how the PA is performing?
- How do I understand from a datasheet just how likely a PA is to self destruct when operating without antenna?
