I was planning to use HMC311ST89 in a new design. I noticed it is shown as Last Time Buy on the ADI's webpage. Is it last time buy or not?
The status info on product pages are up to date, which means HMC311ST89 s at LTB stage. You can use HMC311SC70 or HMC311LP3 which are at production status. If you need ST89 package, you can choose from our many gain blocks in the same package.
If a device moves from production to LTB stage, PCN/PDN is distributed to the authorized sales channels, and they should forward those to you.
