I am planning to build a LDMOS HF power amp. The higher power transistors can easily make >20 dB gain. Power levels out of the SunSDR2 can be turned down so that the SSDR2 + amp meets US power level limit 1500 PEP. But, it would be nice to be able to turn the level to something less ... depending on conditions. I have noticed that the minimum I can turn the power level to is ~1.8 W, but it sometimes is not very stable below 2 W. Can anything be done give better control or better precision to even below 1 W?
