CHA3024 UMS LNA in hermetic package

The CHA3024-FDB is proposed in a 7x7mm2 hermetic metal ceramic package (FDB – SMD type).


This circuit is a wideband 2-22GHz Low Noise Amplifier. It exhibits more than 30dB dynamic  AGC (Adjustable Gain Control) and only 3dB noise figure with a max linear gain of 15dB and a P-1dB of 18dBm.

It is designed for S, C, X, Ku Band Satcom and Radar for hi-rel and on-board applications. UMS also proposes the CHA3024 in a cost effective QFN package for Test & Measument and new space applications..



The circuit is manufactured on a UMS proprietary 0.15µm gate length  pHEMT process.

The FDB package is supported by the Application Note AN0029 which details all necessary information on Surface Mount Hermetic Package FDB type.
