When you are looking at RF receivers from RF Solutions some of the parts have a “P” suffix that does not show on the data sheet The ‘P’ indicates what material the module is built on. P indicates it is built on standard FR4 circuit board material. Without the P suffix it means it is built on a ceramic substrate.
