I'd also suggest -50 or -60 dBm input through the CM to DM transformer.? With gain, -30 dBm is a bit much to assure remaining in the linear region.? Used as the '2222 are in the amp, I have no idea of the IP1 (1 dB output compression power).
And, yes, absolutely use a CM to DM 1:1 transformer on the input.??

While replying to steve I realized I might be close to saturating the VNA input. So I will insert an attenuator after LZ1AQ output and see how it goes.
