Tips:
1. Wanneer de werkfrequentie minder is dan 500 MHz goed vlak, kan het minder dan 1dB maken na zorgvuldige aanpassing. De lagere frequentie is consistentie van de hogere gain.
2de Amplifier werkfrequentie van de lagere limiet is onderworpen aan de ingangs- en outputcapaciteit, de standaardwaarde is 0,1uF, werkt op 0,1 MHz. Verhoog de input- en outputcapaciteit op maat en kan de afsnijfrequentie uitbreiden, zoals de 10uF-capacance kan werken tot 5 KHz.
3de Wanneer de voedingsspanning verandert in 5-8 V, kan hij worden gebruikt als een variabele gain amplifier, verhoogt de toename van de voedingsspanning, geschikt voor radiofrequentie-ontvangst, met behulp van DA-regelstroomtoevoerspanning, om de gain van de versterker te regelen, automatische gain control
4de Wanneer de voedingsspanning in de 8-10 V, gaat het laagfrequentieeinde tot 30 dB tegen, heeft de versterker een lage ruiscoëfficiënt en goede stabiliteit.
5. Wanneer de spanning 12 V is, bereik je de maximale gain het laagfrequentieeinde van 32,5 dB.

Prodotto usato come preamplificatore HF in un ricevitore FT-277 che normalmente non ha di preamplificazione. Segnali passano da 3 a 8 e basso rumore di fondo. Consigliato. Pilotato con alimentazione tramite potenziometro da 500 ohm in serie è possibile variare il livello di amplificazione ma non solo, diminuendo la tensione si ottiene una attenuazione del segnale in ingresso. In pratica variando la tensione si passa in continuità da amplificatore ad attestature. Occhio alla schermatura, è facile ottenere inneschi a motivo dell'elevato fattore di amplificazione. Io l'ho chiuso completamente in una scatoletta di lamierino completamente saldata. Allego toto del montaggio e della scatoletta variatore di tensione.

This amplifier is perfect for increasing the reception of an RTL-SDR dongle. It just about covers its entire tuning range, and then some. I've mainly been using it for shortwave where it has dramatically increased the number of channels received. It's also proven itself well on FM (just don't overdrive the SDR frontend!) and other bands.Just one caveat: you'll need to BYOP (Bring Your Own Power) as its DC-blocking capacitors prevent it getting power from the coax. A nine-volt battery should do the trick however. Interestingly enough though, the amplifier ("N02" INA-02186 perhaps?) is designed to take bias-T power on its output pin (7V max), meaning that those adventurous enough to make some slight modifications might just be able to power the amplifier straight from the RTL-SDR!As mentioned before, this amplifier performs quite well and can in fact attain its advertised +30dB gain. However, do note that, like any other LNA, it will amplify the noise floor somewhat as well.In summary, this amplifier is ideal for anyone wanting an inexpensive upgrade for their RTL-SDR.

I've tried a few of these cheap Chinese preamps and most suck, but this one boosts the signal (and noise of course) from both tuned shielded receive loops and untuned loops on topband and 80m, allowing me to phase receive antennas against my main transmit antenna (3/8 wave inverted Ls on those bands) and null out local interference - or to phase receive antennas against each other. Obviously they work better right by the loop. I used a 12v supply with them. The actual noise figure of the amp itself isn't something I can test.

This product does indeed provide ample amplification, however, the lack of shielding on this product can cause awful amounts of noise to be amplified, too.Additionally, it seems part of the LNA's circuit resonates on a frequency in the FM Broadcast band. With or without and antenna, you can hear several local FM stations on top of each other, no matter where you tune, drowning out everything else.If you can find a way to shield the LNA effectively, it may be of better use, however, as is, I cannot recommend the product.

Il mio non funzionava restituito . Alcuni dicono che e' errata la resistenza da 2,2 k, infatti sostituita correttamente con 220 ohm tutto ok
