BECEN 10 Watt 20dB vaste verzwakker N-type - 10W RF verzwakker 3Ghz 50Ohm (20dB)

I have/had a -20 and -40dB model from this range.After some use at modest power (enough to get it warm), my sample of this -20dB pad measures at about -18dB (not allowing for loss in 0.5m of cable), and it's not perfectly linear (±1dB). But it's good enough for most purposes, especially at this price point.It is possible that it would have measured closer to -20dB when it was new, but I haven't exactly abused it. So, if some of the dissipative elements have gone short (which seems unlikely), their tolerance of moderate power is not what it should be.Though probably not specific to this product, the second spectrum trace shows the importance of ensuring properly tightened connectors! (For avoidance of doubt, that trace demonstrates user error, not product fault.)Do not exceed the rated power. It is not just about heatsink capacity. The -40dB pad just about survived 10.5W, but did not survive 21W for more than 20 seconds or so. When it fails, it won't go completely open circuit (to RF, at least), so unless you're actually measuring something you may not immediately notice that something's wrong. Again, this is user error, not a product fault.Consider a model rated for greater power dissipation if you need as much as -40dB of attenuation.

Piccolo, l'ho testato con un generatore di frequenza e un analizzatore di spettro per ore e l'attenuazione è quella dichiarata con uno scostamento di +/- 0,2 db. All'apparenza sembra la solita cineseria, ma funziona egregiamente e non riscalda quasi per nulla. Forse non è proprio economico ma si trova allo stesso prezzo sull'usato.

Tuve un problema con un repetidor y con este atenuador lo solucione rapido y barato.

El producto cumple lo especificado, perfecto, y a buen precio.
