In this paper, the design of impedance‐matching networks by distributed network synthesis is presented to achieve high‐efficiency characteristics of microwave and millimeter‐wave amplifiers. The transfer function for distributed network structures with an arbitrary electrical length is derived by the Chebyshev approximation. The values of network elements synthesized to match a load impedance are tabulated in terms of the minimum insertion loss (MIL) and ripple parameters. To validate the performance of matching circuits by the network synthesis, the results are applied to the design of an octave‐band microwave transistor amplifier. © 2000 John Wiley & Sons, Inc.
