Overview

CHA2411-QDG RoHS COMPLIANT 20-25GHz LNA GaAs Monolithic Microwave IC In QFN package www.
DataSheet4U.
com Description The CHA2411 is a monolithic Low noise Amplifier in K band providing 26 dB gain from a single bias supply +5V with a noise figure of 2.
5 dB.
All the active devices are self biased on chip.
The circuit is manufactured with a standard GaAs PHEMT process: 0.
25µm gate length, via holes through the substrate, air bridges and electron beam gate lithography.
The chip is delivered in a 24 Leads RoHS compliant QFN4x4 package.
