Design of Dual-Band Antenna Low-Noise Preamplifiers by Multi-Objective Optimization and Its Verification with More Precise Measurement Method
Original language description
The paper demonstrates a practical application of multi-objective optimization in radio-frequency design to achieve a suitable trade-off between the noise figure and transducer power gain of low-noise amplifiers. A variation of the standard optimization method providing asymptotically uniform coverage of the Pareto front is presented. Its usefulness is demonstrated in the design of a dual-band antenna low-noise preamplifier for satellite navigation. Obtained design goals have been verified by measurement. The precision of standard noise factor measurement method (Y-factor method with calibration stage) has been improved by partial correction of the dependence of transducer gain on output impedance of noise source.
