Introduction
The CC1000 is a very flexible and feature-rich single-chip very low-power RF transceiver.
Chipcon has designed the CC1000PP plug-and-play module to serve as a reference layout
and enable very quick prototyping of an RF system.
The tiny CC1000PP module (28x20 mm) contains all RF components required for proper
operation. This includes all the components mentioned in the CC1000 application circuit (see
datasheet for details), as well as a reference crystal and a LC output filter. The layout is
based on a standard, inexpensive 2-layer 1.6mm thick FR-4 PCB process, and has been
carefully optimised by Chipcon. Components are mounted on one side only, the component
side is used for signal routing, and the "solder" (reverse) side is used for a ground plane.
The CC1000PP layout can easily be used as a reference layout by importing it into a PCB
CAD program. Chipcon provides the layout in the industry-standard Gerber format. To
download the files, please visit the Chipcon web site.
As the CC1000PP module contains only the components required for operation, the layout
does not require major modifications when used to make a custom PCB, the user can merely
delete the connector pins at each end of the module. But it is very important that the
component placement, routing and vias are not altered if the same performance is to be
achieved.
If a four layer PCB is to be used, either the two top layers should be used for the RF part, or
layer 1 and 4. Layer 4 should then be the ground plane and layers 2 and 3 should be masked
off.
In a ready-built form, the CC1000PP is ideal for quick prototyping. The module may be
connected to a prototyping board or PCB containing the rest of the system. The CC1000 can
in this way be tested in a complete system without having to create a custom RF PCB layout.
Full documentation is provided for this module, including schematics and PCB layout. This
information can be downloaded from Chipcon's web site.
