2018年4月10日 · I have been working with the AD8302 for a while now and have created a handy equations sheet to help me remember what I did to work out how the various calculations are derived. This sheet shows how return loss, reflection coefficient, SWR, complex load impedance and mismatch loss are calculated using data from the AD8302.

2014年1月26日 · in that thread I saw the log amp which are new for me, I red about them and I found them interesting (even the AD8302 use that logic for the gain and phase measurement) did you try them, if so do they give good result. also do you think that the DC offset will affect the impedance since I am going to feed the DUT with sine wave from 0 - 5V so a ...

2023年6月10日 · I see no plausible reason for, and have found no examples in testing of, these other delays to phases varying, so they can be ignored as constant when using phase diferences to know which half of angular positions the rotor is in. P.S. the AD8302, very good value on those adapter boards, cheaper than the chip itself. Will give that a go if ...

2017年4月1日 · That's what I'm using at the moment actually. I built this and use it with a 50R terminator: 1n270 + 4.7M (or 4.3 - can't remember) resistor (gives rough RMS voltage), a couple of capacitors, a header pin and some RG-174.
