INTRODUCTION
THE PICDEM™ Z MRF24J40 2.4 GHz DAUGHTER CARD
Appendix C. PICDEM™ Z 2.4 GHz RF Card
This appendix describes the PICDEM Z MRF24J40 2.4 GHz Daughter Card. Topics
discussed in this chapter are:
• The PICDEM™ Z MRF24J40 2.4 GHz Daughter Card
• Schematic
• PCB Layout
• PICDEM Z MRF24J40 Daughter Card Bill of Materials
• PCB Antenna Details
The PICDEM Z MRF24J40 2.4 GHz Daughter Card (AC163027-4) is shown in
Figure C-1. It features the MRF24J40 transceiver IC, all passive circuitry, PCB
antenna, and optional SMA connector footprint. It is designed to plug into the PICDEM
Z Motherboard, or to any application, using a 12-pin connector or Explorer 16
Development Board using the side edge connector.
The PICDEM Z MRF24J40 2.4 GHz Daughter Card is a good platform to evaluate an
inverted F-type PCB antenna. The optional SMA connector can be populated to
evaluate external antenna options or to connect to test equipment for measurement.
The PICDEM Z MRF24J40 2.4 GHz Daughter Card may be used as a reference
design. The Gerber files are available for download on the at Microchip website
http://www.microchip.com/wireless/ and on the PICDEM Z CD-ROM.

SMA connector for connecting to an external antenna or test equipment. The
PCB antenna is connected by default. To enable the SMA connector and disable
the PCB antenna, removed capacitor C38 and move it to position C8.
