Figure 30.

Evaluation board (EVB4G) matching network (MATCH_EVB4G.dsn)

For differential to single conversion, the 50 to 100

Ω Johanson balun is recommended

(3700BL15B100).

Divided by 2 output

If your application does not require a balanced to unbalanced conversion, the output

matching reduces to the simple circuit shown below (

Figure 31), which illustrates a

differential to single-ended output network in the 1.65 - 2.2GHz range

(MATCH_LC_LUMP_2G_DIFF.dsn). You can easily use this solution to provide one single-

ended output that terminates the other output at 50

Ω with a 3dB power loss.
