Ka-Band and Q-Band Low Noise Amplifiers

ABSTRACT:ENGIN-IC, Inc. proposes a Phase 1 study that reviews multiple foundries to determine the best processes to support Ka-band and Q-band low noise amplifiers with exceptional linearity, gain flatness, and return loss performance for space applications. The study will include active load pull testing of transistors for each studied process to support the development of accurate transistor non linear models. Utilizing the results from these measurements and novel matching network structures, ENGIN-IC will develop highly linear LNAs into two separate processes that achieve the objective noise requirement of 2 dB at +70 C while improving linearity performance significantly over other commercially available product. A space qualification plan will also be developed for execution under a future phase of the program.BENEFIT:The completed projects will significantly improve linearity performance compared to other LNA products currently offered while achieving the noise figure requirements. These will enable significant improvements in receive dynamic range. ENGIN-IC will offer the product in its standard product catalog as both bare die and packaged devices with both military and space qualifications. There are numerous applications that will utilize the developed technology including satellite communication systems, point to point and multipoint radios, various military radar receivers, and many more.
