Abstract :
A novel method for the design and testing of a low noise receiver is presented. This procedure utilizes the receiver´s unmatched antenna characteristics to serve as the tuning element to achieve a low noise figure match. A microwave circuit simulator is employed to use these characteristics in the design of a 5.75 GHz integrated receiver. The receiver has a measured minimum noise figure of 0.4 dB and 11 dB of gain. Excellent agreement between simulation and measurement exists demonstrating the viability of the design technique.
