Nonlinear transmission line CPW MMIC

Abstract

The paper presents the design, modelling and manufacturing of a new type of MMlC a nonlinear transmission line which consists of 45 Schottky diodes monolithically integrated in a CPW based on GaAs. A four mask technological process was developed, using a special hyperabrupt n-n+profile on a semiinsulating GaAs substrate.

A k-band broadband monolithic distributed frequency multiplier based on nonlinear transmission line

“…The GaAs NLTL is a monolithic circuit, consisting of CPW TL with a high characteristic impedance of Z 0 and periodically at spacing L distributed PSVDs with reverse bias and exhibits nonlinearity from voltage-variable capacitance of PSVD and dispersion characterized by Bragg cutoff frequency from the periodic network. [12,13] The NLTLs design procedure, based on the large-signal model of PSVD, is similar to one adopted by Li and is followed as that in Ref. [14].…”
