Abstract :
We report the performance of a wideband image rejection microwave downconverter which maps 0.8-8.8 GHz signals into intermediate frequencies between 1-2 GHz. Measurements performed on the system reveal an image rejection of greater than 150 dB and a spur free dynamic range of 106 dB/Hz/sup 2/3/. In addition, spurious signals present in the original system have been removed.
