The CC2541EM-TPS62730EM reference design contains schematics and layout files for the CC2541EM-TPS62730EM module. The reference design demonstrates good techniques for CC2541 decoupling and RF layout. For optimum RF performance: the reference design should be copied accurately. This is a 4-layer reference design with an SMA antenna connector for RF output matched to 50 ohm. Along with that: it shows the proper way to supply the CC2541 with the TPS62730 DC/DC converter for current savings of up to 30% in active mode. The TPS62730 converter is controlled by the CC2541.
