Noise figure is routinely used by system and design engineers to ensure optimal signal performance. However, the use of mixers in the signal chain creates challenges with straightforward noise-figure ...

Modern digital receiver/exciters (DREX) used in radar and communications systems are capable of significant self-testing in a production factory environment. Long past are the days where the analog ...

This paper presents two approaches to improve the performance of RF low noise amplifiers (LNAs) and downconversion mixers. One approach is for noise enhancement and the other is for improving flatness ...

2G, 2.5G, and 3G technologies all have a share of the wireless market and there is a strong demand to integrate all formats into each wireless handset. At the same time, there is a growing trend to ...

You can never have enough sensitivity or gain in global navigation satellite system (GNSS) receivers as long as the noise figure is good. In fact, high gain and low noise are the key specs for GPS and ...

Building 2.5/3G mobile phones may seem like an exciting venture. But, once you dive into the designs, they are an RF and mixed-signal nightmare. These mobiles must support high-speed Internet access, ...
