Third order Intercept Point (IP3)

Thrid order intercept point(IP3) is a used to quantify weak non-linearity in an amplifier or RF system. It is an interpolated point where the fundamental component power curve meets the third order intermod(IMD3) component power curve. Consider a nonlinear amplifier whose input-output characteristic is represented by a 3rd order polynomial […]

Wireless Receiver Sensitivity

Receiver sensitivity is defined as the minimum signal power (Pi,min) at which a receiver can detect a signal while providing an adequate SNR at analog receiver output (BER at digital receiver output). This is minimum detectable signal(MDS) power. In a multi-standard receiver, the sensitivity requirements vary depending on mode of […]
