Hi there,
I purchased **broken link removed**, which is supposed to work between 1MHz and 800MHz. I made some stability tests connecting the amplifier output to a spectrum analyzer and leaving the input open. It turned out that I see a strong peak around 700 MHz, meaning that the amplifier is oscilating. Varying the gain control causes a small frequency shift in the peak. Any ideas of what is causing the oscilation? What is the best way to track the root of the problem?
