Your cart is empty.This N type attenuator has a 50 ohm impedance and is a DC to 3GHz 2Watt power rating. Attenuators are used in a variety of applications, including lab testing, antenna testing, and more. This particular model is designed for frequencies from DC to 3GHz, with a 1-40db attenuation range.

Flat -3db to over 3 ghz. You will get some vswr ripples though.

Note: I did not test the capacity of this attenuator to stand 2 W. Presumably that means with 2.2 W input, delivering 200 mW to the 50 Ohm load, this attenuator will safely dissipate 2 W. It's definitely hefty enough to handle that, and I don't doubt that it can, but I did not have time to measure that aspect.I ordered and tested the 10 dB version of this product. I put the attenuator on my PicoVNA and tested to 6 GHz, though it's specified as a "3 GHz" attenuator. Depending on your tolerance for impedance mismatch (i.e. VSWR), I think this attenuator is usable to 6 GHz, but at 3 GHz it's definitely a credible attenuator.You can see from the attached plots that attenuation is quite close to 10 dB; at 3 GHz it's 10.54 dB. Below 1 GHz it stayed between 9.9 and 10.2 dB. If you want to push it to 6 GHz, the highest error I observed was attenuation of 11 dB at 4.3 GHz.As to VSWR, it stayed better than 1.46:1 in both directions, up to 3 GHz. The product page says VSWR max of 1.2:1 up to 3 GHz, so according to my measurements, that spec is not met. I'll take off 1 star on the rating for that. Stay below about 1.5 GHz if you need VSWR that good. The worst I saw up to 6 GHz was 2:1 at about 5 GHz.The price of this when I ordered it was quite modest for an attenuator like this. I'd say the specs are not stellar, but for a lot of applications, this is a great attenuator to use.

I got a 10dB attenuator and my nanoVNA says it's -10dB. Can't complain at all.Didn't push the power dissipation envelope, but since there's no heatsink fins, I can believe the 2 watts max rating.

Nothing to dislike as it seems to work as it should. I rarely work above 600 MHz so that's what I tested it to. From 1 - 600 MHz it reasonably flat, plenty good enough for my needs. Keep in mind this is a relatively inexpensive piece of equipment so don't expect HP quality but this unit seem pretty good.

This review is for ARELATER 2Watt N Connector Attenuator,DC to 3GHz,50 Ohm,1-50db (10dB).I tested this using a Rigol 832 with tracking generator. The unit's calibration is current. After connecting a jumper and normalizing the TG output, I inserted the 10dB attenuator. The test results sweeping from 100kHz to 3.2GHz are shown on the attached trace. Note that the vertical scale is 1dB/division and that there is a +2dB offset to allow easy viewing. The actual attenuation is 10dB +0.07dB -0.74dB. The average, ignoring the slight ripples is about -10.31dB. Also note that the maximum measurement uncertainty for the Rigol 832 is 0.8dBWhile not perfectly flat, this is fairly reasonable performance for the average user at a very reasonable price. +/- 1 or even +/-2 dB is not going to matter for most applications, like filter analysis or amplifier testing.I did not test the unit's power dissipation rating of 2W, but given the space available inside a N connector, body, this is likely OK.Overall, this is a good price and will allow you to test many circuits without damaging the input circuits of your test equipment. This unit will serve me well for routine tasks on the bench.

The attenuation is reasonably flat according to my NanoVNA-H, which is only good to 1.5GHz. It was well packaged in a foam-lined tin. The center conductor appears to be aluminum.
