Hi everyone. I've purchased an LNA from Minicircuits and I don't get any signal from it.
The LNA is connected on an antenna and its range is 1250-1650mhz.
Connecting the receiver on the antenna with no LNA, I can receive the usual signals from the FM radio, GSM, GPS and so on, but I just get line noise with the LNA. Powered or not makes no difference, it basically acts as a full-band filter.
I don't have a signal generator to thoroughly test the L band, but I'm suspecting the unit is defective and I'm not sure how to test it. Could have I inadvertently fried it despite using a regulated 12v power supply? Impedance between VCC and GND is ~6 ohms, hasn't changed between when I received it and now.
