Application and design notes
New RF4CE application note: Power consumption for RemoTI
Corrected due to wrong description in June newsletter:
This new application note shows how to calculate battery life for real life remote control applications and explains how to get years of battery life with the TI RemoTI development kit.

AN082 -- Two-way audio communication using the CC1110 or CC2510 and the TLV320AIC26
This application note describes a two-way audio communications link based on CC1110 or CC2510 SoC transceivers connected to TLV320AIC26 codecs via the I2S bus. Example software is included.

AN072 -- Using the TAI-SAW TA0801A SAW filter and external PA with the CC11xx radios in the 868 MHz band
The application note examines using the TAI-SAW TA0801 SAW filter with the CC11xx series radios and an external power amplifier to increase performance while maintaining ETSI compliance.

AN081 -- Johanson Technology balun optimized for CC2530
The file accompanying AN081 contains schematics and layout files for the CC2530 realized with only one part from Johanson Technology interfacing the antenna; see AN081 for details. The Johanson Technology part realizes the balun-, filter- an impedance matching-function and is custom made to be operated with CC2530. 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 or easy connection to instruments for measurements.
