TDK Corporation balun optimized for CC253x CC2530TDKBALUN-RD (ACTIVE)
See the Important Notice and Disclaimer covering reference designs and other TI resources.
The CC2530EM reference design contains schematics and layout files for the CC2530 and contains one part from TDK Corporation interfacing the antenna (documented in AN104).
The TDK Corporation part realizes the balun-, filter- an impedance matching-function and is custom made to be operated with CC253x. CC254x and the CC85xx PurePath wireless family. The reference design demonstrates good techniques for CC2530 decoupling and RF layout. For optimum RF performance, the reference design should be copied accurately. This is a 2-layer reference design with a SMA antenna connector allowing operation with single ended 50 ohm antenna for easy connection to instruments for measurements.
