Other Parts Discussed in Thread: CC1310, CC1190
Hi Experts, the customer is evaluating CC1120 products.
They have some questions.
"We are looking for long range communication solution. We expect to add external FEM in order to achieve >20dBm TX power at 900MHz for US market.
We have following questions about Ti 900MHz transceiver
1. Which chipset support antenna diversity? Transceiver or MCU make decision?
2. Which chipset support external FEM?
3. What is enhanced wake-On Radio? Which chipset support it?
4. What is coding gain in CC1120? What is the data rate limit in coding gain? Have any other chipset support it?
5. Do they support CCA or LBT? Could we tune the threshold of CCA or LBT
6. What is the max payload length? Is it 256byte?
7. What is the sensitivity difference between 2GFSK and 4GFSK at same data rate?
8. In CC1120 datasheet page 7, what is the difference between Packet mode and Transparent mode?
9. Do you have a RF driver for measuring sensitivity (1% BER) in demo board?
10. Did you add LNA in 900MHz chipset? What is the best sensitivity at 900MHz after adding external LNA?"
Thanks
