Corrections to “Design and Fabrication of Broadband Hybrid GaAs Schottky Diode Frequency Multipliers” [Dec 13 4442-4460]

The block diagram shown in Fig 33 of the above-named paper [ibid., vol. 61, no. 12, pp. 4442–4460, Dec. 2013] is incorrect. Instead of series resonators, it should contain parallel resonators. A corrected version is provided here as Fig. 1. In the continuous text of the above paper [p. 4451, col. 2, line 38] it reads "MSL half-wave series resonator," which is incorrect. It should read "half-wave MSL parallel resonator."
