## Overview

The Akozon RF Amplifier Module is a compact, high-performance low noise amplifier designed for frequencies from 0.01 to 4GHz. Delivering a typical gain of 21dB and a low noise figure of 1.3dB, it enhances radio receiver sensitivity and wireless communication clarity. Built with durable, corrosion-resistant materials and featuring immersion gold-plated SMA connectors, this module ensures reliable, long-term operation in demanding environments.

## Description

Power supply voltage: typical +5V (typical current value 125mA). Gain: typical value of 21dB@1.9G (Different frequency gains are slightly different ). Input output impedance: 50 Ω Maximum Output power: P1dB +22dBm typical, +39.5 dBm Output IP3. Specifications: Bandwidth: 0.01-4GHZ Noise coefficient: 1.3dB Size:32 x 23mm/1.26 x 0.91inch Weight: 5g Package Included: 1 x RF Low Noise Amplifier

Review: BROAD BAND RF AMPLIFIER - Overall a functional amplifier my initial target frequency is 2.4ghz unfortunately for my purposes the gain tails of and produces only 12db. Below 1ghz the gain starts to rise sharply towards 20db, I have not tested it below 144mhz yet, test gear is Anritsu and calibrated. The SMA connectors are only soldered on the top surface with way to much solder and the flux is not removed. I have reworked the SMA and modified the circuit to reduce the bandwidth to SHF, the gain has improved to 17db at 2.4ghz good enough for my purpose. It would have been easier and a lot quicker to chain two amplifiers together but I do not have room in the case.
Review: not impressed - Very poor amplification of signal runs extremely HOT tested at 14 050 Mhz and 50.150 Mhz

## Features

- 【Application】The low noise amplifier is widely used for high frequency or intermediate frequency preamplifier of radio receiver, high sensitivity amplifying circuit of electronic detection equipment, ransceiver wireless communication card, and tower mounted amplifier (TMA), combiner, repeaters, and distal/digital wireless broadband head equipment, etc
- 【Excellent Design】This low noise amplifier has a wideband range of 0.01-4GHZ, and large dynamic range +21dB, maximum output power: P1dB +22dBm typical, and the noise factor is as low and 1.3dB
- 【Durable Use】This high gain low noise amplifier with wide frequency range, high gain, low noise figure. Durable material provides long term corrosion protection, even in salt air enviroments
- 【Enhanced Connection】The rf amplifier module adopts the process of immersion gold, make the printed circuit surface is stable with color, brightness and smooth coating, good welding property. Ultra bandwidth, high frequency inductors and capacitors without resonant points
- 【Standard Connectors】Standard SMA female connectors are suitable for connecting most devices. The process of immersion gold improves reliability, not easy to corrode and fall off, and have beautiful appearance

### ⭐⭐⭐⭐ BROAD BAND RF AMPLIFIER
*by O***B on 4 December 2024*

### ⭐⭐ not impressed
*by P***C on 5 April 2025*

Very poor amplification of signal runs extremely HOT tested at 14 050 Mhz and 50.150 Mhz

### ⭐ Design change since Amazon photo make the device useless
*by T***T on 19 May 2024*

Photos on the Amazon site show through plated holes for 5V and Gnd. Fitting pins to connect power would be easy hence my decision to buy this device. Delivered item has only a pad for 5V. This makes it next to impossible for a home hobbyist to connect power. Whilst adding a ground plane is a good thing, removing the hole for 5V isn't very well thought through.
