Receiver image rejection
Webb17 aug. 2024 · With further integration combined with digitally assisted processing, the I/Q channels can be well matched, leading to much improved image rejection. The receiver section of the recently released AD9371 is a direct-conversion receiver and shown in Figure 2—note the similarity to Figure 1c. Webb2.0 IMAGE-REJECT ARCHITECTURES The basic objective of an image-reject receiver is to process and suppress the image-tone without utilizing an explicit, external filter. A useful …

http://qtwork.tudelft.nl/~schouten/linkload/rfreceivers1.pdf Image response (or more correctly, image response rejection ratio, or IMRR) is a measure of performance of a radio receiver that operates on the superheterodyne principle. In such a radio receiver, a local oscillator (LO) is used to heterodyne or "beat" against the incoming radio frequency (RF), generating sum and difference frequ…
Webb9 jan. 2015 · This is identical to the math that governs image cancellation in image reject and single sideband mixers, the only difference is that one of the 90° phase shifts occurs at the transmitter in an IQ scheme, while they are both at the receiver in the image reject/single sideband scheme. WebbThe receiver's dual antenna diversity helps avoid signal dropouts, and its durable metal frame and chassis can either be used on a tabletop, or rack-mounted with optional rack mounting hardware.
