CHA2411-QDG
RoHS COMPLIANT
20-25GHz LNA
GaAs Monolithic Microwave IC
In QFN package
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.
