G. Bartolucci et al., DESIGN CONSIDERATIONS FOR TUNNEL-DIODE NONLINEAR TRANSMISSION-LINES, International journal of infrared and millimeter waves, 16(10), 1995, pp. 1719-1732
A tunnel diode non-linear transmission line has been investigated for
second and third harmonic generation purposes. Design criteria are giv
en and performance predictions have been obtained simulating the singl
e diode behavior by means of a polynomial expression, An optimization
of the non-linear transmission line as a harmonic generator has been o
btained as a function of the number of diodes, their separation distan
ces and the bias voltage.
