Device Overview

General Description

The INV-0026 is a broadband pulse inverter that operates over a 1 MHz to 26.5 GHz bandwidth. This inverter features fast rise and fall times and low insertion loss. Inverters use both magnetic and capacitive coupling to create an inverted version of a voltage signal. In the frequency domain, inverters introduce a broadband 180° phase shift relative to the input signal, while maintaining a flat group delay to ensure signal integrity.
