Abstract:In this paper; we evaluate a new design of a previously presented agile single-chip receiver front-end intended for a digital beamforming X-band smart skin array antenna. Firstly; by using a two-stage low noise amplifier in each filter section of the tunable active filter used in the front-end; a igher filter gain and selectivity as well as a lower filter noise figure can be achieved at the expense of a smaller filter tuning range. Secondly; the 1GHz-IF double balanced mixer also utilized in the front-end has been re-optimized to achieve higher image rejection and lower conversion loss. As a result of the filter and mixer RF performance improvements achieved the re-designed front-end can exhibit at least 50-85dB of image rejection; up to 13dB of conversion gain; a 6.4dB minimum value noise figure and 60-65dB of spurious-free dynamic range over the 7.6-8.6GHz agile receiver bandwidth; respectively.
