This simple method, commonly used by RF engineers every day, is effective for creating a fast change of frequency range in a demo circuit, when you only have something close to work with. Your ability to use Freescale RF Power products as drop-ins is increased! In addition to being able to purchase a demonstration board, you can download any of the available DXF files for the PCB layout and order the board and list of materials for your production line. In many cases, you may be able to save money by choosing, testing, and qualifying your own list of less costly components. The initial design work is done with a Freescale demo board! The tuning, manufacturing and qualification process is all that is left to you. Thanks for choosing Freescale RF Power!
