See TI application sheet p.9 **broken link removed** As i said its a resonent ferrite based transformer.

The datasheet for the obsolete old IC says to use a Toko transformer that is also obsolete.

EDIT: When I press "Post Reply" then nothing happens. Why?
Then after a minute my reply is doubled. Why?
 

You could try using a pulse isolation transformer, this would give give you your isolation, it could also do some impedance matching(~ 10:1 required). This would have to have a high pass filter as well with a pass band tuned to your carrier frequency (which you do not give)
