The IR-4509 is an image reject mixer that performs single sided downconversion, or "image reject" conversion, and offers excellent image rejection across broad bandwidths. This broadband mixer spans 4.5 to 9 GHz on the RF and LO ports with an IF from 50 to 90 MHz. IR series mixers have generally been replaced with MMIQ mixers with superior performance, repeatability, and availability. IR series mixers are still used in legacy systems and are suitable for laboratory use.
