https://community.nxp.com/t5/Other-NXP-Products/Output-matching-circuit/m-p/1457430#M14020 <P>Hello NXP community,</P><P>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.</P><P>Thank NXP community!&nbsp;</P><P>&nbsp;</P><P>Best regards,</P><P>Aaron</P><P>&nbsp;</P> Thu, 12 May 2022 17:52:56 GMT Purchase 2022-05-12T17:52:56Z https://community.nxp.com/t5/Other-NXP-Products/Output-matching-circuit/m-p/1457430#M14020 <P>Hello NXP community,</P><P>I am trying to find out how the output matching circuit for BLF188XR 50V CW 2-30 MHz amplifier (attached data sheet) is working.
