The 2450 MHz Reference Circuit is shown for design purposes only. An
evaluation board is not readily available for this application. The reader can
obtain an FP1189-PCB2140S evaluation board and modify it with the circuit
shown to achieve the performance shown in this reference design. Only two
component changes are required (C4 and L3) from the FP1189-PCB2140S
evaluation board.
