EVM or Error Vector Magnitude is a measure of how the measured constellation points deviate from the ideal locations. EVM(%) = sqrt(P_error / P_reference) * 100 P_error...Read More
Here follows a basic tutorial on LNA design described by example using ADS. The steps involved usually follow the sequence: Define LNA requirements Select device(s) Find good bias...Read More
IBM’s DOORS software is a great tool to capture and manage product requirements, test requirements and test evidence for large systems. I have used it extensively on an...Read More
Linecalc is a useful utility that is bundled with Keysight ADS, and is used to estimate the performance of pcb transmission lines. To demonstrate what it can do,...Read More
IP3, or third order intercept point is a way of stating how non-linear a system is. For example, often seen on datasheets, it is an easy metric to...Read More
PAPR or Peak to Average Power Ratio is a way of characterising how far the waveform envelope peak exceeds the waveform mean. It can be represented by a...Read More
One of the calculations that is required when designing a receiver or transmitter line-up of circuit blocks is cascaded Noise Figure (NF) and cascaded Third Order Intercept Point...Read More
