I have read the note: Differential to single-ended: What happens when you use only one differential amplifier output
and I am ok with no common mode rejection and losing 3dB gain and the harmonic is not the primary goal.
But when I set up the TINA model and simulated the output with a transmission line, I got significantly reduced bandwidth, which is not acceptable.
I have configured the amplifier with unity gain and the shunt resistor.
The bode plot amplitude part seems ok, and has a peak at ~3-4GHz, but the phase part, the VF1 (after the transmission line) goes much faster than others.
For the impedance matching, I added a 39.8 ohm (tweaked between 39 to 40, according to the datasheet, there is a 10 ohm in the package. )
The transmission line model is found in this forum (https://e2e.ti.com/support/tools/simulation-hardware-system-design-tools-group/sim-hw-system-design/f/simulation-hardware-system-design-tools-forum/234485/lossless-transmission-line-in-tina-ti).
Am I missing something?
Thanks
