摘要

A lumped lossy circuit is synthesized by means of the transformation introduced by L. Zhu et al. (ibid., vol.36, no.12, p.1614-20, Dec. 1988). The circuit contains two different kinds of lossy branches that include arbitrary nonuniform reactive resistors as well as lossy inductors and capacitors. This approach can be used to synthesize a lumped lossy matching network more flexibly than previous techniques. An example is presented to show the application of the synthesis of the lumped lossy matching networks for compensating the device gain roll-off with frequency in the design of a broadband monolithic microwave integrated FET amplifier. The advantages of the technique are seen by comparison with the amplifier designed by Zhu et al.
