A circuit topology for a frequency doubler consisting of a distributed ampliﬁer work- ing under nonlinear regime is analyzed analytically and characterized experimentally. Fully- distributed circuit topologies for the phase shifter used to realize the gate and drain artiﬁcial transmission lines of the distributed ampliﬁer are proposed. For these types of phase shifters, it is shown that efﬁcient rejection of the output odd harmonics is possible, but also low ripple of the output power level on the output second harmonic is obtained. The proposed frequency doubler has been designed for central input frequency equal to 5 GHz, and the designed cir- cuit has been fabricated, too. The experimental conversion loss for the fabricated frequency doubler is less than 4 dB and 7 dB, when the power level to the input is imposed to –1 dBm and 5 dBm, respectively, while the input frequency is between 4 and 6 GHz.
