Note: Reference Application Note M513 for reel size information. The exposed pad centered on the package bottom must be connected to RF and DC ground. (For PQFN Packages) Pins 10 & 29 must be isolated -Vee is produced internally and requires a .1µF cap to GND. Generated noise is typical of switching DC-DC Converters. 1 ADVANCED: Data Sheets contain information regarding a product M/A-COM Technology Solutions • North America Tel: 800.366.2266 • Europe Tel: +353.21.244.6400 is considering for development.
