A Sensitivity Analysis of Radio Architectures Employing Sample and Hold Techniques
Abstract: This letter describes the use of sample and hold devices for frequency conversion within a radio. By assuming a perfect multiplier, a model is developed in order that the noise figure of a sample and hold device can be predicted. The results show that sample and hold devices have higher noise figures than mixers and hence their use can give rise to reduced receiver sensitivity.
