Thread Summary

                The user is designing a matching network for the LT5537 at 10.7MHz and requested the S11/impedance data. The support engineer provided the input impedance model as a 1.94K resistor in parallel with a 2.59pF capacitor at 11MHz. The user also sought clarification on the 240Ω termination resistor used in the datasheet example at 200MHz, questioning its effectiveness in achieving maximum power transfer.

Hello support team,


I am trying to design a matching network for the LT5537 from input of 330 ohm at 10.7MHz.


Can you please provide data of its S11/impedance around this frequency?


My intention is to use its differential input in order to get maximum sensitivity.


Thanks!
