High Dynamic Range HF Low Noise Amplifier

I designed and built a High Frequency (HF) 1.5 - 30 MHz Low Noise Amplifier (LNA). The LNA was to have a low noise figure, preferably less than 5 dB, and a high OIMD3. I'm pleased that after a decade of experimenting, I finally have an amplifier to be proud of. The final specs are: NF = 2.1 dB worst case, Gain = 10.5 dB, and OIP3 of greater than 61 dBm.
