Walfront RF Amplifier, 50K-2GHZ Broadband Amplifier Low Noise LNA Amplifier for FM Radio, Remote Control Receiver, Cable TV Signal Amplifier, [email protected]

First ... I'm not an RF guy. I bought this amplifier to use with a set of H probes for EMI troubleshooting. And, I just opened it and powered it up. I don't remember seeing much in the specs, but this is what I have found:It has (as expected) a 50 ohm input impedance and drives a 50 ohm load just fine.With the 50 ohm source and load, the gain is about 63 (36 dBV) at 1 MHz.The output starts to go nonlinear at about 40 mV p-p sine wave.So far I like it.
