CHA2441-QAG a new K-band LNA

UMS is expanding its K-Band offer with the launch of a new LNA. The CHA2441 QAG covers 22 to 26GHz frequency range. This circuit delivers 25.5dB gain from a single bias supply of +3.3V and offers an excellent noise figure of 2.5dB. It also features a very low DC consumption of 50mA at 3.3V with on chip self biased transistors.

With its reduced size 16L-QFN 3x3, the CHA2441-QAG is unique. It is particularly suitable for automotive, radar and ISM applications.

This product is manufactured with a 0.25μm pHEMT process and is supplied in RoHS compliant SMD package.
