JAJSNJ7A March 2023 – June 2024 TRF0208-SEP
ADVANCE INFORMATION
デバイスごとのパッケージ図は、PDF版データシートをご参照ください。
The TRF0208-SEP is configured as an S2D amplifier. The section close to TRF0208-SEP output is an attenuator pad that is meant for robust matching. The section close to the AFE7950-SEP is the matching network for the AFE7950-SEP ADC input that is channel dependent. The matching components are chosen based on the AFE7950-SEP return-loss data and some final optimization because the manufactured board parameters can influence the exact component values needed.
Table 7-2 shows the bill of materials (BOM) values of the design for a channel that is matched to center frequency of 8.2GHz.
