X-Band and Ka Band Low Noise Block Downconverter
Phase I tasks will determine the integration plan for the block downconverters used in satellite communication systems. The anticipated advantage of using GaN HFETs for limiter/LNA combination will be quantified. The concept will be verified by device characterization, modeling and a prototype amplifier demonstration. MMIC amplifiers will be designed for the final goals, to be completed and fabricated in Phase II. A precise device model, both noise and large signal, of 0.15 micron gate GaN HFETs will be developed and used in the LNA design. Two amplifiers will be designed for X-band and Ka-band with the performance goals consistent with requirements. In parallel to completing the LNA design, a single-stage prototype amplifier will be built to demonstrate critical key features in the LNA design, such as noise figure and high-power survivability. Feasibility of integrating other block downconverter components will be studied and a recommendation will be made. BENEFIT: This technology is applicable to military satellite communication and radar systems. Commercial Application: High performance, affordable downconverter components would find wide application in commercial satellite communication systems and mobile communications.
