I wonder if what you are looking at is not a ceramic package at all but one of the new plastic packages being offered. Amkor calls these Micro Lead Frame (MLF) components. Other manufacturers call them BCCs. That lead count in that body size is one of the sizes available in Amkor's MLF packages. The lead pitch is 0.5mm. I believe that Amkor may have land patterns for that package available on their website.

I'm looking at one from RF MicroDevices - and their datasheet is lacking in the land pattern department (very helpful...) I need some advice re: land pattern design. IPC land pattern calc is no use - it's not a standard LCC design.
