I am the chief design engineer for an RF product on sale world wide that uses Hittite microwave parts. We have recently been hit by Analog announcing that HMC916 (active tripler) is obsolete and I have just finished a new design to work around. I now find HMC788 is obsolete and will have to re-engage to find a work around. Could you please make a statement about what other Hittite parts you are going to drop without regard for existing designs (I know of no drop in replacement). We also use HMC311 - will this become obsolete?
