AN1838_Mixer 2x2 and IP2COMMUNICATIONS CIRCUITS HIGH-SPEED SIGNAL PROCESSING Application Note 1838: Dec 27, 2002 Mixer 2x2 Spurious Response and IP2 Relationship This application note details the definitions for 2nd order intercept point (IP2) and 2x2 spurious response, parameters frequently found in RF-related component datasheets such as mixers. Reading through this application note will enable the user to convert IP2 to its corresponding 2x2 spurious response value and vice versa. When mixer data sheets provide 2nd-order response information in their AC electrical characteristics table, they will either refer to second order intercept point (IP2) performance or 2x2 spurious rejection performance. The purpose of this application note is to show the relationship between these two parameters and its applicabil……
