... RF2619 Measurement Reference Plane IN IN sets the balanced output impedance and C2 serve dual purposes. L1 serves as an output bias choke, and C2 serves as a series DC block. In addition, the values of L1 and C2 may be chosen to form an impedance matching network if the load impedance is not 1k ...
