We study several parasitic effects on the implementation of a Josephsonradiation comb generator (JRCG) based on a dc superconducting quantuminterference device (SQUID) driven by an external magnetic field. This systemcan be used as a radiation generator similarly to what is done in optics andmetrology, and allows one to generate up to several hundreds of harmonics ofthe driving frequency. First we take into account how assuming a finite loopgeometrical inductance and junction capacitance in each SQUID may alter theoperation of this device. Then, we estimate the effect of imperfections in thefabrication of an array of SQUIDs, which is an unavoidable source of errors inpractical situations. We show that the role of the junction capacitance is ingeneral negligible, whereas the geometrical inductance has a beneficial effecton the performance of the device. The errors on the areas and junctionresistance asymmetries may deteriorate the performance, but their effect can belimited up to a large extent with a suitable choice of fabrication parameters.
