How do I get the 0-30mhz gain, noise figure, 1db compression, and similar specs for thsse general purpose chips: The datasheets seem to stop below 100mhz. Here are the chip model numbers I need help on for the 1-30mhz range: BGU6104, BGU7003W, and BGA2869. Or if you recommend a different LNA for better low noise specs at these freqs, please let me know.
