AFE7900 RF sampling analog front end Texas Instruments
TI AFE7900 RF sampling analog front end (AFE) Texas Instruments is a high-performance, broadband transceiver. The device integrates four RF sampling transmitter chains, four RF sampling receiver chains, and two RF sampling feedback chains. The operating frequency of this device is up to 7.4GHz, which can realize direct radio frequency sampling in the L, S and C frequency bands, and no additional frequency conversion stage is required. This increase in density and flexibility enables high channel count and multitasking systems.
The TX signal path of Texas Instruments AFE7900 supports interpolation and digital up-conversion options, which can provide up to 1200MHz signal bandwidth for four TXs or up to 2400MHz for two TXs. The output of the DUC drives a 12GSPS DAC with a mixed-mode output option to enhance the second Nyquist operation. The DAC output includes a variable gain amplifier (TX DSA) with 40dB range, 1dB analog and 0.125dB digital steps.
