ADL5920 has internal amplitude detectors that can be calibrated to measure forward and reflected power magnitude. There is no provision for phase angle measurement.
order the DC2847A-KIT on the bottom of adl5920 product page.
the ADL5920-EVALZ SCH. is in the adl5920 datasheet, page 23. there's no user manual for this board, but it only requires 5v on VPOS to power the board up.
Take a look at ADL5920 which is a scalar reflectometer with integrated coupling (www.analog.com/ADL5920). Also take a look at this circuit note(www.analog.com/cn0374). The ideas in there could be used to make a vector reflectometer.
I got this working in the past.
I have a new computer. I ran the quikeval but upon its completion I get a screen in which it says "The USB-to-Serial Controller is not connected"…
Any application note for connecting 55dBm signal to ADL5920?
I recently received a DC2847A (or EVAL-ADL5920-ARDZ)
On this page: https://wiki.analog.com/resources/eval/user-guides/eval-adl5920-ardz
it says to come to this EngineerZone to request the tools/GUI...
So - how do I get it?
here's the gerber files for the EVAL-ADL5920-ARDZ.
What is a release schedule for ADL5920? Will it be ready for autumn?
Or should we stay with conventional directional couplers along with LTC5583 IC?
Looking at the schematic for the eval board
I see U2 is a 24LC025-I/ST
I assume that holds calibration data fro the board?
If not what is it for?
If so, is it preloaded at the factory?
