The Third Order Intercept Point, or IP3, serves as a pivotal parameter characterizing the behavior of RF systems. At its core, IP3 delineates the point at which the third-order intermodulation distortion’s power (IMD3) coincides with the extrapolated linear output power …
The design of an RF system consists of many different blocks, and sometimes it might include two amplifiers to amplify the weak signal. For example, the below figure shows the design with LNA and an additional amplifier for amplifying the …
