INPUT AND OUTPUT PORT MATCHING

Rev. E | 39 of 53

The ADL6337 has four variants for four operating frequency rang-

es. Each variant has different input port matching schemes. The

ADL6337-A requires external matching components for a 50 Ω in-

put impedance to achieve the return loss specification, and external

matching components are required for 100 Ω source matching. See

Figure 122. The ADL6337-B, the ADL6337-C, and ADL6337-D do

not require any external components to match the 50 Ω input impe-

dance. However, the external matching components must match

the single-ended 50 Ω load impedance only for the ADL6337-C and

ADL6337-D. Additionally, the external matching components must

match the 100 Ω input source impedance. See Figure 123, Figure

124, and Figure 125. Note that the matching components can be

changed due to the board structures and materials.
