CC1312R7: Would like to know the value of local frequency of receiver's mixer

Hi Shunsuke,

The local oscillator frequency will depend on the receive frequency and on the intermediate frequency of the PHY that is being used. What RF frequency and PHY would be used?

Hi Diego,

Thank you so much for your reply. I have listed the answers.

RF frequency: 1216MHz, 1216.5MHz, 1217MHz, 1252MHz, 1252,5MHz, 1253MHz

PHY: CC1312

Best regards,

Hi Shunsuke,

By PHY I meant the RF physical layer. For the CC1312 we have multiple PHYs that have been characterized with different data rates to transmit/receive the data.

Reduced list from SmartRF studio:

The intermediate frequency can change depending on the PHY used. Which PHY or PHYs would be used?

For the IF frequency, see chapter 10 in https://www.ti.com/lit/an/swra682/swra682.pdf. This also point to the relevant table in the TRM. 

Hi Diego-san,

PHY: Narrowband 4.8 kbps, 2 kHz Deviation, 2-GFSK, 10.1 KHz RX Bandwidth.

Best regards,
