Device Overview

General Description

NLTL-6273 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 beyond 40 GHz. NLTL-6273 is fabricated with GaAs Schottky diode based varactors on a 2.28 mm x 3.13 mm substrate. Both wire bondable die and connectorized modules are available.
