We report the performance of a wideband image rejection microwave downconve
rter 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 g
reater than 150 dB and a spur free dynamic range of 106 dB/Hz(2/3). In addi
tion, spurious signals present in the original system have been removed.
