AD 8302 in 75 ohm system - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2010 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 2010, 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.

I want to use AD 8302 for gain & return loss measurement with 75 ohms impedance.

in application note there is input terminating resistor 53 ohm which i will change to 75 ohms. Further i will change input attenuators to match 75 ohms. This application is on page 20 & 21 of AD 8302 datasheet.

waiting for guidance from fellow members.

Sounds OK. You should keep the characteristic impedance to 75 ohm.

Good luck!
