Using LimeSDR for transmission of 3G waveform

Dear All
i want to transmit a 30 Mhz signal in 3G band . from 2110 Mhz to 2140 Mhz . total separtion is 30 Mhz on TX1_2 or TX2_2 . Center frequency is 2125 Mhz . any idea how to do it on LimeSDR ?

Best Regards

Using TX1_1 of LimeSDR , transmitted 2100 MHz signal , and checked it on spectrum analyzer . after adjusting gain and other things , I saved .ini file. As registers have been saved with some hex values, i want to load those register values in flash . that whenever i power up limeSDR it should configure with these settings. how to do this . ?
