... Figure 16 illustrates differential balance at the input and output using a transformer balun. Input and output baluns are recom- mended for optimal performance. Much of the characterization for the ADL5331 was completed using 1:1 baluns at the input and output for a single-ended 50 Ω match. Operation using M/A-COM ETC1-1-13 transmission line transformer baluns is recommended for a broadband interface ...
