How to build Power sensors using Schottky diodes - RF Cafe Forums

RF Cafe Forums closed its virtual doors in late 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2012, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. Regardless, there are still lots of great posts in the archive that ware worth looking at. Below are the old forum threads, including responses to the original posts.

hi!

I want to build a power sensor with an operating frequency range from DC to 8 Ghz. The maximum power level is 20dBm. Is it possible to build one for this power level using Schotkky diodes. are there any special Schotkky diodes available for this purpose.

Hi,

there is no problem to do a power sensor for this band or power. What you should consider is to put some attenuator before the diode and there are plenty of diodes that could be used!
