TGL4201-03

Overview

The Qorvo TGL4201-03 is a fixed 3 dB wideband attenuator designed for ultra-wideband applications. It operates from DC to greater than 40 GHz, providing a 31.5 dB attenuation range with over 25 dB of gain control range across the frequency spectrum. The device features excellent return loss exceeding 15 dB and handles up to 20 dBm of power. Constructed as a die with on-chip grounding vias, it utilizes GaAs technology for robust performance in demanding RF environments.
