We are considering LT5575 as an image reject mixer in a receiver application. For that application, harmonic levels (2LO-2RF, 3LO-3RF etc.) are also important. Previously, we were using a pair of HMC915 double balanced mixer in order to form an image reject structure but it is obsolete now. It had a spurious table as below figure and harmonic levels were very good compared to other mixers which exist now. Does LT5575 has that kind of spurious table data? We need at least 65 dBc surpression of harmonics when input RF level to nearly +5 dBm. Is LT5575 suitable for that application? If not, can you suggest any other mixer that is suitable?
