Hi!I am designing a 200W, IMD3< -40dBc
amplifier for 30-88MHz application, I am going to using MRF6VP2600 of
freescale.The test circuit(225MHz) are as follows:
There are
two baluns(T1 and T2) , they are coaxial line transformers, is there
anyone known the parameters of these baluns(length and Zo)?
(Baluns
are made by Comm Concept, and I have email Comm Concept company, but
they didn’t reply me)
Since the Comm Concept company didn’t reply
me, is there any other products I can use to substituted for T1 and
T2?
Maybe I have to make it myself, can you give me some reference
on how to make a balun like this?
