## Overview

The NooElec SAWbird+ H1 is a premium, self-contained LNA module optimized for hydrogen line (21cm) SDR applications at 1420MHz. Featuring dual ultra-low-noise amplifiers sandwiching a custom high-performance SAW filter, it achieves a noise figure as low as 0.8dB and over 40dB gain within a 65MHz bandpass. Designed for versatile powering via bias tee, microUSB, or header, it includes EMI shielding for interference-free reception. Made in North America, it comes with a 2-year warranty and direct manufacturer support, making it the go-to choice for serious SDR enthusiasts and professionals aiming to capture the faintest cosmic signals.

## Description

For full product details, please visit the product page at nooelec.com!SAWbird+ H1 is a self-contained LNA module designed for hydrogen line applications at 1.42GHz. It has a very high attenuation outside of the 65MHz bandpass region, centered near 1.42GHz, and a minimum of 40dB of gain at the frequency of interest. Nominal current draw is 120mA. SAWbird+ H1 does NOT contain the same 50 ohm reference that is on SAWbird+ H1 Barebones. As such, this module has a lower noise figure of ~0.8dB vs ~1.05dB of SAWbird+ H1 Barebones. 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 an EMI shield to separate the LNAs from external interference. 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 XTR) 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. It is important to note that some SDRs would have their ESD protection diode tripped by the LNA when powered externally. You can still use the LNA with these SDRs of course, but you would need to install a DC block between the LNA and SDR. This can be as simple as a low-distortion, high-quality capacitor in series with the RF path, should you prefer a DIY solution.

Review: SAWbird H1 - I got this SAWbird H1 with a new desing casing. I used it with standard 2.42 GHz parabolic dish (it resonates also at 1.42 GHz). It works really well and the Hydrogen line is clearly visible!
Review: Works well - Works very well to specification.

I got this SAWbird H1 with a new desing casing. I used it with standard 2.42 GHz parabolic dish (it resonates also at 1.42 GHz). It works really well and the Hydrogen line is clearly visible!

### ⭐⭐⭐⭐⭐ Works well
*by A***R on 18 May 2021*

Works very well to specification.

### ⭐⭐⭐⭐⭐ Rendimiento acorde al esperado
*by D***A on 27 April 2020*

El LNA llegó acompañado de un latiguillo adaptador USB/conector de barríl de 5,5mm para la conexión de alimentación externa y un barrilete SMA macho/macho. El rendimiento de nuestra unidad honra los valores anunciados: ganancia sensiblemente superior a los 40dB en la banda de trabajo, con un ancho de 67MHz. Como se aprecia en las imágenes, la banda de trabajo está sensiblemente desplazada hacia abajo respecto a la frecuencia de funcionamiento nominal. Ahora, ¡a montarlo en una antena!
