Abstract
Noise analysis of a subsampling mixer structure based on current signal sampling is performed. The calculations show that a promisingly low noise figure can be obtained. The results of the analysis are verified by high-level simulations and measurements of a test circuit designed for quadrature downconversion from a 1st IF of 44.87 MHz to a low IF of 13 kHz
