Device Overview

General Description

NLTL-6273SM is a MMIC non-linear transmission line (NLTL) based comb generator. This NLTL offers excellent phase noise performance over a low 0.7 to 5 GHz input frequency range with output tones to 24 GHz. NLTL-6273SM is fabricated with GaAs Schottky diode based varactors and packaged into a surface mount 5x5 mm2 QFN.
