Output matching circuit

[Purchase]

Hello NXP community,

I am trying to find out how the output matching circuit for BLF188XR 50V CW 2-30 MHz amplifier (attached data sheet) is working. I have found some circuits do not require T2,T3 transformers and behaves similarly. Just wondering if there's a simpler way to understand what T2 and T3 are actually doing here? More reading material (books, articles, etc) would be most excellent.

Thank NXP community! 

Best regards,

Aaron
