CHA2411-QDG_15 Datasheet, PDF (1/10 Pages) United Monolithic Semiconductors – 20-25GHz Low Noise Amplifier

CHA2411-QDG
20-25GHz Low Noise Amplifier
GaAs Monolithic Microwave IC in SMD leadless package
Description
The CHA2411-QDG is a K-band low noise
amplifier providing 26dB gain with a noise
figure of 2.5dB from a single bias supply
+5V.
The circuit is manufactured with a pHEMT
process, 0.25µm gate length, via holes
through the substrate, air bridges and
electron beam gate lithography.
It is supplied in RoHS compliant SMD
package.
