Third order intercept formula

Webthird order intermodulation product (slope of 3), the third order intercept point can be calculated by measuring both the fundamental signal and the intermodulation product at just one input level, and applying the following formula: TOI=Pout + IPdBc / 2 Where TOI is the third order intercept point, P out is the output WebFor a given frequency, knowing the third order intercept point allows calculation of the approximate level of the third-order IMD products as a function of output signal level. Figure 4 below shows the third order intercept value as a function of frequency for a typical wideband low-distortion amplifier. 50 50 OUT 50 40 30 20 10 1 10 100

http://testedgeinc.com/docs/ip3.pdf Webamplifier, or other mildly nonlinear device. An intercept point can be defined for a second-order, third- order, fifth-order, or other product. For a diode mixer, as a rule-of-thumb, two-tone third-order intercept point (IP3) is approximately 15 dB above the 1-dB compression point. For a FET mixer, the rule-of-thumb is 10 dB. So, if the ... WebSep 10, 2008 · Notes/Equations. To measure the third-order intercept point, you must setup a Harmonic Balance simulation with the input signal driving the circuit in the linear range. Input power is typically set 10 dB below the 1 dB gain compression point. If you simulate the circuit in the nonlinear region, the calculated results will be incorrect. much more different
