RF Trace Layout Design

The RN2903 modular transmitter is certified with a PCB edge SMA connector and micro-strip trace layout as shown in

Figure 5-1 and Figure 5-2. The left side RF path is not used for this module. The host PCB can follow these trace design

to maintain compliance under the modular grant (FCC) and certificate (IC). Gerber files are available on the RN2903

product web page at www.microchip.com/rn2903.
