## Overview

The NooElec SAWbird+ NOAA is a premium, self-contained LNA module designed specifically for capturing high-quality weather images from NOAA satellites at 137MHz. Featuring a custom high-performance SAW filter and dual ultra-low noise LNAs, it delivers a minimum 30dB gain within a narrow 5MHz bandpass for exceptional signal clarity. With three power input options and robust EMI shielding housed in a sleek aluminum enclosure, it offers versatile, interference-resistant operation. Ideal for professional SDR users seeking reliable, crisp satellite data reception.

## Description

Full product information can be found on the product page at nooelec.com. SAWbird+ NOAA is a self-contained LNA module that allows you to capture beautiful weather images from NOAA satellites. It has very high attenuation outside the 5MHz bandpass range, centered around 137.5MHz, and a minimum gain of 30dB within the bandpass range. The rated current consumption is 180 mA. The SAWbird+ series contains two extremely low noise LNAs arranged around a specially designed high-performance SAW filter with the desired frequency. Each LNA module has 2 EMI shields to separate each sensitive LNA from external interference. M3 mounting holes are also available to mount the PCB in your custom case or project using standard hardware. Each module offers 3 different power options, but you should only use one power option at a time! The recommended power supply via the SMA output port (for bias - T - capable SDRs such as the NESDR SMArTee) is 3V-5V DC. If you don't have a bias-T enabled SDR, you can also use the external power options via the micro USB port or the power input head (0.1" socket). The recommended external power input is 3.3V to 5.5V DC. Although the SAWbird has a protection circuit for surge conditions and voltages of up to 12V DC should continue to work and do not damage the device, use for a longer period of time is not recommended. Conditions would not fall under the standard 2 year warranty.

Review: Great Product - Product arrived as promised and works as specified.
Review: Produces high gain and crisp images - Make sure you install this in the right direction. It isn’t obvious. The white light will go on when it is installed in the right direction. SDR sharp shows significant increase in gain and the images come through very crisp. I use this with RTL SDRv3 and enables bias tee using their Windows application. If using with SDR#, close SDR# before launching rtl_biast.exe. You will probably have to change the device ID from 0 to 1 like I did. If it works then you will get Found Rafael... message then the program quits. Plug in the LNA and the light should turn on. That’s it.

## Features

- SAWbird+ NOAA is a self-contained LNA module designed for capturing beautiful weather images available from NOAA satellites (~137MHz)
- The module uses 2 ultra-low-noise LNAs and a custom high-performance SAW filter centered at the frequency of interest
- SAWbird+ NOAA can be powered in 3 ways: via bias tee, through the on-board microUSB connector, or through DC barrel connector with the included USB to DC connector adapter
- Though compatible with most SDRs, we recommend use in conjunction with NESDR SMArTee (available on desertcart, product ID B079C4S2BT)
- Includes free aluminum enclosure, male SMA to male SMA adapter and USB to DC barrel connector adapter. Full 2 year warranty and support direct through Nooelec!

## Questions & Answers

**Q: Will this work on a brushless dc dewalt 7.25 inch circular saw?**
A: Yes.  It also works on horror films with Jigsaw as the primary antagonist.

**Q: Which is actual voltage it requieres to operate?**
A: It operates from 5 Volts DC, but it pulls quite a bit of current.  The Bias-T in my SDR (RSP2-duo) will not power it. I use an external Bias-T for power.

**Q: how far away from Smartee can this be placed and still be powered properly?**
A: It depends on the cable type used, but very far in practice.

**Q: Does the "Input" end connect to the antenna?**
A: The end with the mini-USB power connector connects to the antenna.

### ⭐⭐⭐⭐ Effective little LNA
*by K***N on December 28, 2024*

Works very well. I use this with my SDRPlay RSP1B for NOAA and Meteor weather satellites. Did have two small issues with it. 1. Caused a local FM Broadcast staion near me to overload my receiver. Used a Nooelec Flamingo BCFM filter to resolve that. 2. Since its the SAWbird+ it drew more current than my RSP1B would deliver so I had to power it via USB. I would recommend, if you have the same receiver, to get the SAWbird NOAA (not the plus version), its current draw is lower and the SDR has no problem with it.
