WebIP2 (Second Order Intercept Point) and IP3 (Third Order Intercept Point) are used to measure performance of the non-linear devices. The figure depicts block diagram of IM2 (Second Order Intermodulation Product) measurement setup. It shows W a and W b as fundamental frequencies. WebA precise calculation requires knowing the equation of the input/output power transfer curve of each device, which is typically a high-order polynomial that would be very difficult both to ascertain and also to apply mathematically. A well-known rule-of-thumb is to subtract 10 to 15 dB to the IP3 value to estimate the P1dB value.
