Webbias-Ts for an IP3 measurement. The bias-T must cover the frequency range of the envelope, or the tone spacing. If the bias T does not pass this frequency component properly the envelope will be distorted and the measurement can be incorrect. This shows up as unsym-metry between the lower (IM3L) and upper (IM3U) distortion products, http://www.circuitszoo.altervista.org/cadence_IP3.html

Web10 dec. 2012 · IP3 is usually defined for 20 or 30 dB ratio between the "nominal" output power and the first "other" side bands. When you vary mixer input level (s) smoothly, you will see that the above ratio varies by more dB than the dB change of the input level. WebFrom the slopes in Figure 4, we can see that IP2 can be calculated from one set of measurements as: IP2 = 2(Pin) – IM2 where all quantities are in dBm. This classical IP2 equation has a resemblance to the much more often used IP3 equation for a 2-tone test, which is: 2(IP3) = 3(Pin) – IM3 P out IP2 Pin IP2 Pin IM2 eagle creek townhomes lees summit
