TYPICAL APPLICATION CIRCUIT

Figure 41 shows a typical application circuit for the ADF7024. All

external components required for operation of the device,

excluding supply decoupling capacitors, are shown. This example

circuit uses a combined transmit and receive match. The bottom

of the LFCSP has an exposed pad that must be soldered to

ground on the PCB. The component values for the matching

and harmonic filtering are dependent on the RF band and the

matching topology. For more information, see the ADF7024

Hardware Reference Manual, UG-698, which is only available as

part of the ADF7024 design resource package.
