Using this app, you can: Build a cascade of RF … WebbIP3 (3rd-order intercept) is meaningless here, as IMD in an ADC follows a quasi-1st-order rather than a 3rd-order law. The transfer and IMD curves diverge, and never intersect. In a conventional receiver, IP3 is the convergence point of the transfer and IMD curves.

"WebbThe answer to the question was as follows. ( For experienced receiver designers this is old hat of course.) The SFDR is a specification which allows a reviewer to gauge the range of input/output signals that a receiver can handle while still in a linear range of operation. The basic mathematical definition is: SFDR = (2/3) x (IP3 – Noise floor) " - Receiver ip3

However, as will be shown later for IP2 and IP3, if you are careful when choosing the powers used for P and ΔP, the actual result is not sensitive to differences in the power levels of the two input tones.

WebbIn my opinion many receivers have too much gain before the selective filter, and the down-conversion mixer can cause severe IMD products when listening to signals close to strong stations. I have tested some receivers that give good +15 to +20dBm IP3 performance at 50kHz spacing but very poor results in the region of -30dBm at 5kHz spacing.
