Tool/software:
Thank you for your previous answer. I have some more:
1. Regarding your previous answer, do you think that combined the signals from both ports using short wires (A+ to B+, A- to B-) allows me to cheaply get extra 3dB power? (assuming I will find a way to properly route these nets). I think that this what you originally meant in your answer but I was not sure...
2. Do figures 17, 18, 155, 156 refer to a single ended output power or to a differential one?
3. According to RF OUTPUT specification, a single ended output power at 2GHz with OUTxPWR=15 is 5dBm.
According to to figure 18 (156) it seems that for 2GHz, with OUTx_PWR=15, the output power is 6dBm. Is it a typo in the datasheet?
Thanks,
Roy
Hi Roy,
I just tried connecting two same polarity pins together, I didn't get 3dB more power.
All power measurement is single-ended.
5dBm is a typical number, it is not surprise to see 1 or more dB variation.
If you are looking for 10dBm power, I think a gain block is the most straight forward solution. TI has several low cost gain blocks.

How much power gain did you get when you combined both differential outputs? (I can use a single differential-port output power to drive a mixer's LO. Any small increase will improve the mixer behavior, so this is why I don't look for active power amplifier)
Thanks,
Roy
