8.2.2 TRF1208 in a Transmit Chain

This section describes an RF transmit chain in which the TRF1208 works as a differential-to-single-ended converter that converts the DAC output of the AFE7950 into a single-ended signal that drives a PA or a mixer.

GUID-20211012-SS0I-B88H-M0FR-47MB9NHCM549-low.svgFigure 8-6 TRF1208 in a Transmit Chain With the AFE7950

The previous figure is a generic schematic of a design in which the TRF1208 is used with the AFE7950 in the transmit chain. The exact values of the components depend on the frequency band for which the AFE7950 front-end is matched.
