Can any microcontroller implement BPSK or QPSK modulation technique?
Thanking You...!

Hi,
Please see:
There is a (non-TI) blog post talking about implementing BPSK on one of our devices (the CC1110-CC1111), but it's quite sparse on the details: https://www.tablix.org/~avian/blog/archives/2016/06/ultra_narrowband_and_bpsk_on_ti_cc_chips/
So the short answer is there is not a lot a support for these modulation schemes - what is supported is detailed in the linked E2E threads.

Zack
Please can you rephrase the questions? I am not sure what you are trying to ask in your latest post.

Zack.
1.How to convert digital data into RF data?
That is one of the functions of the transceiver or system-on-chip (SoC).
2.What are the parameters need?
It's unclear what you are asking for here - please clarify.
3.Any IC has generate Modulation technique ?
If you are asking if we have any ICs that implement BPSK or QPSK, please see my answer to your original post regarding our Wireless Connectivity products.
1. The CC1110-CC1111 contains the CC1101 transceiver. The details we have made public are available in the CC1101 Datasheet: https://www.ti.com/lit/swrs061 - Figure 9 in Section 6 provides a simplified block diagram of the transceiver.
2. You could try an approach similar to that described in the following threads, at least for RX, on the CC1120 transceiver (using the raw data from the ADCs in I and Q paths):
As the TX is based on direct synthesis of the RF frequency there is no IQ DAC, so this approach is not possible in TX and so you will be more limited in your options (BPSK in TX detailed in the original reply). You asked about both BPSK and QPSK, so your exact requirements here are important. For example, the CC1101 supports MSK (also known as differential offset QPSK).
