Hello and hope you can help with 2 basic queries.

 

Query 1

Its not clear from either the Si3735 (SSOP variant) datasheet or the AN383 Antenna design paper if I need to provide 2 AM coils (on the ferrite Rod) - One for MW and One for LW (switched in to the AMI based on band selection) or simply one coil in the inductance range as described in the AN383 ?

 

Query 2

If I need two coils and also want to provide SW (as per AN383) as well as MW and LW, which coil (MW or LW) would be the candidate for  the AMI inductor to ground (page 46/47 of AN383) ?

 

Thanks in advance.

 

regards


Gordon
