We are planning to use ADL5920 in our antenna matching circuit. Our radio works from 1MHz to 100MHZ and the connected antenna is mono-pole and tend to have impedance other than 50 ohm.. We are planning to insert an tunable LC matching circuit in the path just before antenna. The impedance measurement of connected antenna is required for our matching algorithm to insert exact matching circuit. We found that ADL5920 can measure FWD, REV and VSWR measurements. Can we measure antenna impedance with these values else is there any alternate/additional circuit needed to accomplish this task..
