Allows for selecting attenuation from 1db-42dB in 1dB increments. Includes values of 1dB, 2dB, 3dB, 6dB, 10dB and 20dB. The maximum power is 2W. Attenuator accuracy is / - 0.1dB from DC to 3GHz and / - 0.4dB from DC to 6GHz. Max VSWR is Laser-etched values ensures longevity of labeling. Full 2 year warranty! Review: Como es habitual, recibido en tiempo garantizado. En cuanto al comentario respecto a los atenuadores, adjunto imágenes con los resultados medidos en el caso del de mayor atenuación (-20dB) que es el que mayor desviación del valor nominal pudiera presentar. Las imágenes corresponden a las calibraciones: 1 a 60 MHz 130 a 170 MHz 400 a 480 MHz 10 KHz a 4,4 GHz Las tres primeras medidas arrojan resultados con valores más o menos lineales. Donde más se aprecia una ligera “no linealidad” es en la calibración de 10 KHz a 4,4 GHz donde se puede apreciar que a partir de poco más de unos 2 GHz hay una ligera oscilación en el valor medido. Por supuesto que no son elementos de laboratorio, pero por el precio que tienen son aceptables para trabajos no profesionales. Review: Die Teile weisen sehr gute Werte auf. Messergebnisse passen exakt zu meinem VNA. (kein R&S) Sehr gut verarbeitet. ## Features - A convenient package of 6 different 50Ω SMA in-line attenuators - Includes values of 1dB, 2dB, 3dB, 6dB, 10dB and 20dB, which allows for selective attenuation of anywhere between 1dB-42dB in 1dB increments! - Fantastic accuracy of /- 0.1dB through to 3GHz - The values are laser-etched to ensure longevity of the labeling for the life of the devices - Full 2 year warranty direct through Nooelec ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07YYMT65T | | Brand Name | NooElec | | Customer Reviews | 4.7 4.7 out of 5 stars (175) | | Item Dimensions | 40 x 20 x 10 millimeters | | Item Weight | 31 Grams | | Manufacturer | Nooelec Inc. | | Model | SMA Attenuator Kit | | Mounting Type | Surface Mount | | UPC | 616469146618 | | Voltage | 5 Volts | ## Product Details - **Brand:** NooElec - **Item dimensions L x W x H:** 40 x 20 x 10 millimeters - **Manufacturer:** Nooelec Inc. - **Mounting type:** Surface Mount - **Voltage:** 5 Volts ## Images ![SMA Attenuator Kit - Bundle of 6pc 2W 50 Ohm SMA In-Line Attenuators Provides Highly Linear Attenuation from 1dB to 42dB in 1dB Increments. 1dB, 2dB, 3dB, 6dB, 10dB & 20dB Adapters Included - Image 1](https://m.media-amazon.com/images/I/714q+myCbEL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***R on 20 June 2024* Como es habitual, recibido en tiempo garantizado.

Messergebnisse passen exakt zu meinem VNA. (kein R&S) Sehr gut verarbeitet. ### ⭐⭐⭐⭐⭐ Review *by C***O on 1 February 2021* Ho acquistato 2 set di attenuatori al prezzo di 45.95 euro ciascuno, consegna puntuale e valore nominale degli attenuatori come da descrizione. Li ho caratterizzati a 144, 432 e 1296 MHz con VNA calibrato e questi sono i dati che ho ricavato: Precisione sul valore di attenuazione S21: entro +- 0.1 dB per tutti i pezzi tranne i 2 attenuatori a -6 dB (-5.83...-5.89 dB misurati) e 1 attenuatore a -20 dB (-19.84...-19.93 misurati). Return loss S11 e S22: per 144 e 432 MHz sempre migliore di -40 dB (SWR 1.02). A 1.2 GHz sempre migliore di -35 dB (SWR 1.04). Per i miei scopi sono ottimi! ## Frequently Bought Together - Nooelec SMA Attenuator Kit - Bundle of 6pc 2W 50 Ohm SMA in-Line Attenuators Provides Highly Linear Attenuation from 1dB to 42dB in 1dB Increments. 1dB, 2dB, 3dB, 6dB, 10dB - NooElec SMA DC Block in-Line 50 Ohm 50kHz-8GHz Connector Blocks DC Voltage from Your Radio or RF Test Equipment.
