Figure 33. Differential and Single-Ended Output Configuration
The THS5651A can be easily configured to drive a doubly terminated 50-
cable. Figure 34(a) shows the
single-ended output configuration, where the output current IOUT1 flows into an equivalent load resistance of
25
. Node IOUT2 should be connected to ground or terminated with a resistor of 25 . Differential-to-single
conversion (e.g., for measurement purposes) can be performed using a properly selected RF transformer, as
shown in Figure 34(b). This configuration provides maximum rejection of common-mode noise sources and
even order distortion components, thereby doubling the power to the output. The center tap on the primary side
of the transformer is connected to AGND, enabling a dc current flow for both IOUT1 and IOUT2. Note that the
ac performance of the THS5651A is optimum and specified using this differential transformer coupled output,
limiting the voltage swing at IOUT1 and IOUT2 to
±0.5 V.
