You can analyze small-signal gain and noise figure nearly exactly, and come pretty close to modeling large-signal performance, such as predicting one-dB compression point. Everyone and their little brother has created an Excel spreadsheet for performing Cascade analysis.
16 Ιουν 2018 · If you know how to use Excel and you know anything about cascaded system calculations, then you know how to use RF Cascade Workbook™. This is significantly easier and faster than using the multi-thousand dollar simulators when a quick system analysis is all that is needed.
20 Μαρ 2018 · We will explain the Cascade Noise Figure analysis using the spreadsheet of a simple 9-stage receiver as an example so you can learn how to design an RF circuitry concerning Noise Figure. You can download the spreadsheet here.
28 Ιαν 2018 · Noise Figure (NF) is a measure of how much a device degrades the Signal to Noise Ratio (SNR), with lower values indicating better performance. The noise contribution of each device in the signal path must be low enough that it will not significantly degrade the Signal to Noise Ratio.
25 Μαρ 2003 · Excel has FFT and IFFT functions. With a little more work these circuits can also give you time domain waveform information. For the RC circuit you could analyze current glitches on a bypassed power line; for the op amp you could look at the waveform's edges and overshoot.
What are tone tags/indicators? Tone tags/indicators are short text at the end of a message to let the reader know how the message is meant to be read, clear up any misunderstanding, or simply tell what the tone is.
In this article we will discuss how to analyze the Cascade Noise Figure using a universal spreadsheet template that will help you calculate and optimize the resulting NF in no time. Therefore, you can design a receiver with expected Noise Figure without any hesitation.
