11.2.2 Transformer
The configuration of the transformer circuit is determined by the input frequency. The
configuration shown in Figure 15
would be suitable for a baseband application.
The configuration shown in Figure 16 is recommended for high frequency applications. In
both cases, the choice of transformer is a compromise between cost and performance.
