I was visiting the ADI website and checking up on a couple of key Hittite parts. Saw that the HMC525 and HMC620 have been removed from the websites list of IQ and IRM mixers. After searching their part number specifically, I was able to find their product page and noticed the lifecycle status had changed to: Not recommended for new designs. This is very concerning since these parts are core to several of our products. What information can you give me as to whats happening here?
There were some other IRM's similar the the 525 and 620 operating at higher frequency ranges we were considering to use in other products. I don't have their part information and am having trouble finding them on the ADI website. What do you recommend?
