JAJSNJ7 March 2023 TRF0208-SEP
ADVANCE INFORMATION
The TRF0208-SEP is configured as a D2S amplifier. OUTM pin of TRF0208-SEP is terminated on 50-Ω and OUTP is taken out as the SE output. The section close to TRF0208-SEP input is an attenuator pad, which is meant for robust matching. The section close to AFE7950 is the matching network for the AFE which is channel dependent. The matching components are chosen based on the AFE return-loss data and some trial and error since the board parameters can influence the exact values.
Table 8-3 provides the BOM values of the design for a channel that is matched to center frequency of 8.2 GHz.
