The lower frequency the higher gain consistency. 2.Amplifier working frequency of the lower limit is subject to input and output capacitor, the default value is 0.1 uF, working to 0.1 MHz. Increase the input and output capacitance appropriately, can extend the cut-off frequency, such as 10uF capacitance can work to 5KHz. 3.When the power supply voltage changes in 5-8 v, it can be used as a variable gain amplifier, gain increases with the increase of the power supply voltage, which suitable for radio frequency receive front-end circuit, using DA control power supply voltage, to control the gain of the amplifier, automatic gain control 4.When the power supply voltage in the 8-10 v, the low frequency end gain up to 30 db, at this time the amplifier has a low noise coefficient and good stability. 5.When the voltage is 12 v, reach maximum gain, the low frequency end gain of 32.5 dB. Package included: 1 * 0.1-2000MHz RF Wide Band Amplifier Module 30dB High Gain

I have used the amplifier and it works. I don't have the calibrated instruments to offer any real analysis of performance, but when I applied power and connected to a 10 MHz signal source I could see a lot of amplification. I discovered a reference that said if the amplifier is operated with a voltage between 5-8 V it operates as a variable gain amplifier. I discovered that to be the case.

It was hard to resist for the price so I thought I'd give it a shot. I tested it with my nanoVNA. First, gain went from 32.2 dB at 1 MHz to 31 dB at 500 MHz. (I didn't test any higher.) Next I wanted to see if it stayed linear up to the +10 dBm output specification. FIrst I checked with an oscilloscope at 30 MHz. The sine wave looked pretty good. I also looked at 50 MHz and it still looked good. I followed this with a check using my tinySA. The spectrum looked good at 10 dBm out and even a bit higher. From 30 MHz, the 2nd harmonic was at -45 dB, 3rd at -31 dB and 4th at -40.5 dB.This is all with a 12 VDC supply. Supply current was from 22 mA to 25 mA. The gain dropped by 2 dB as I dropped the supply voltage from 12 VDC to 9 VDC.

Not a high-end pre-amp, but good enough for prototyping superhet receivers. Front end overloads easily.

No amplification whatsoever. Felt the main IC and it was red hot. DOA. Sent back.

With this device, i can pick up the emissions from my little regenerative receiver and actually see what frequency the receiver is tuned to (since the receiver has no calibrated tuning dial).With an AD-8307 dBm meter (measures power less than 1 mW), i verified that this pre-amp is putting out only about 0.1mW total RF power. The tinySA can handle only up to 10mW (10dBm), so this pre-amp is safe to use with my tinySA.

Reviews are varied, but I ordered 2 and they worked just fine.

Works best on all 50 ohm impedance receiving systems > 10 mhz...A post-Lna Preselector helps to optimize S/N reception..Very satisfied with Lna product..Started right up on 12 vdc battery. ..Makes the difference to hear the weak stations...

Used regulated power supply to be certain not to damage unit and it provided ZERO amplification. Tried unit on several antenna / radio combinations and it provided no amplification what so ever in fact it caused a total loss of signal on a 900 MHz receiver setup. Save your money, Garbage.............
