Chip has been obsolete for years, but there are still quite a number around.
I have of the luxury of VNA and was re-purposing an early 2000's amplifier which required stability.
Under any circumstance, the LM3875 seems to need a 15 to 20pF compensation capacitor across the feedback resistor. The design in the datasheet may not have been checked up to 10MHz.
