What is RF Isolator, How to choose it ?
An RF Isolator is a two port device that is unidirectional, means it passes the RF signal in one direction only. It is used protects RF components in a system […]
Addition of Power Levels
This tools adds the power levels in dBm, Means you give input first power level in dBm and second power level in dBm, it gives the SUM output in dBm. […]
dB , dBm Terminology
I keep seeing people using the terms “dB” and “dBm”, interchangeably, when they actually mean very different things. So, here’s a little background on the correct usage of the terms. […]
Passive Inter-modulation (PIM)
Passive Inter-modulation (PIM) is the generation of interfering signals caused by non-linearities that occurs in passive components such as antennas, cables, connectors, or duplexers with two or more high-power input signals. […]
Error Vector Magnitude (EVM)
The error vector magnitude (EVM) is a measure of modulation quality of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation points precisely […]
Mobile Phone Architecture
When we say a mobile, it is not just a piece of plastic/metallic body, as it looks from outside, there are lots of different components/modules inside that mobile. This article […]
Noise Figure
Noise figure (NF) and noise factor (F) are measures of degradation of the signal-to-noise ratio (SNR), caused by components in a radio-frequency (RF) signal chain. It is a number by which the performance of an amplifier or a […]
