John: So you need another 10dB of gain between 1 & 5 GHz. I have used Miteq low-noise preamps in the past, but I bought octave-band models and I paid a lot extra for absolute lowest noise figure with about 35dB of gain. I suggest you call Miteq (get the noise figure of your spectrum analyzer first) and see what combinations they recommend. You might need only a 1dB noise figure, with about 20dB of gain, which may mean they have one unit that can span the frequency range.
