Gain Flatness - 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.

I have a measurement that I am not familiar with. I have been asked to perform a Gain Flatness measurement over a frequency range.

I am measuring a coax cable with 2 connectors.

What type of meausrement is Gain Flatness ? How would I set up the VNA ?

Thanks,

Tom

Gain flatness of any applicable device is defined as the variation of a transmission characteristic (S21) over the full operational frequency range, usually at a given temperature, expressed in dB.

Take Care
