## Overview

The Nooelec SAWbird+ NOAA is a premium, self-contained LNA module optimized for 137MHz NOAA satellite signals. Featuring dual ultra-low-noise LNAs and a custom high-performance SAW filter, it ensures sharp bandpass filtering and 30dB gain for superior weather image capture. With versatile power options and robust EMI shielding housed in a sleek aluminum enclosure, it’s designed for professional-grade SDR setups and backed by a 2-year warranty.

## Description

For full product details, please visit the product page at nooelec.com!SAWbird+ NOAA is a self-contained LNA module designed for capturing beautiful weather images available from NOAA satellites. It has a very high attenuation outside of the 5MHz bandpass region, centered around 137.5MHz, and a minimum of 30dB of gain within the bandpass region. Nominal current draw is 180mA. The SAWbird+ series contains 2 ultra-low-noise LNAs sandwiched around a custom-designed, high-performance SAW filter centered at the frequency of interest. Each LNA module has 2 EMI shields to separate each delicate LNA from external interference. There are also M3 mounting holes available to mount the PCB in your custom enclosure or project with standard hardware. Each module allows for 3 different power options, but you should only power with one option at any given time! The recommended power input through the SMA output port (for bias-tee capable SDRs like the NESDR SMArTee) is 3V-5V DC. Alternatively, if you don't have a bias-tee capable SDR, you can use the external power options through the microUSB port or the power input header (female 0.1" header). The recommended external power input is 3.3V-5.5V DC. Though there is protection circuitry on the SAWbird for overvoltage conditions, and voltages of up to 12V DC should still work and will not damage the device, it is not recommended for long-term usage. Kindly note that damage resulting from overvoltage conditions would not be covered under the standard 2 year warranty.

Review: Works as specified, not sure if I need the LNA - This performs pretty much as the datasheet that Nooelec publish. Gain is high, and the passband follows what they say. It's very sharp on the lower side, providing strong attenuation to airband and FM broadcast, but rolls off more gently on the other side, still allowing some of the very strong 153MHz pager signals through. Realistically, I'm not sure the LNA is needed. I get reasonable signal strength for NOAA satellites with just a V-dipole. The high gain means I'm brining up the noise as well as signal, and it's overwhelming rtlsdr dongles. Just a filter might work better for me, but your mileage may vary.
Review: Still learning - I purchased this because it's a recommended product on RTLSDR forums and sites for downloading the weather satellite footage from the NOAA sites over using a generic wideband LNA I have yet to o gain a good image. This isn't the product it's just me because I'm relatively new and still learning. The sawbird filter has an adaptive draw I wasn't powering mine through a USB socket or dc jack I used a bench power supply Initially I had the voltage set as 4.5v however I discovered this was actually too much ( but within range) and it wasn't applying much gain I reduced the voltage down to 3v and it's usage went to 0.35A and then it got about 30db gain in signal So it does work. However I need to take my equipment outside and add grounding straps because I'm getting a lot of electrical interference I also need to bukd a better aerial. Setup filters properly find the right station etc etc

## 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.

### ⭐⭐⭐⭐⭐ Well built device
*by D***L on 18 May 2024*

This filter has a feel of quality about it and it has helped improve the NOAA weather images I can receive using a simple horizontal V aerial. Works best with the filter located at the aerial and powered by a biased T.
