Monolithic nonlinear transmission lines can be employed as ultrashort pulse (1{endash}5 ps rise/fall time) generators to extend ultrashort pulse reflectometry (USPR) to high field tokamaks such as TFTR, Alcator C-MOD, and ITER. Multiple barrier varactor devices have been successfully employed as high power and high speed devices in this application. Monolithic NLTLs can also be employed to simplify moderate pulse reflectometry systems, in which NLTLs may be employed as broadband frequency multipliers. Theoretical and experimental investigations will be presented.{copyright} {ital 1997 American Institute of Physics.}
