## Overview

The SAWbird+ H1 is a premium hydrogen line LNA module centered at 1420MHz, featuring dual ultra-low noise amplifiers sandwiching a custom high-performance SAW filter. Designed for software-defined radio enthusiasts, it offers over 40dB gain with a noise index as low as 0.8dB. Power it flexibly via Bias T, micro USB, or onboard header. Made in North America and backed by a 2-year warranty, it ensures reliable, interference-shielded performance for advanced 21cm band experiments.

## Description

Visit nooelec.com product page for more product details! The SAWbird + H1 is a built-in LNA module designed for 1.42 GHz hydrogen line applications. Very high attenuation around 1.42 GHz outside the 65 MHz band pass area, with a minimum of 40 dB gain at the frequency of the target. Nominal current consumption is 120mA. SAWbird + H1 does not include the same 50 ohm references as SAWbird + H1 Barebones. Therefore, this module has a low noise index of about 0.8dB to about 1.05dB of the SAWbird + H1 barebone. The SAWbird+ series includes two ultra-low noise LNA sandwiched around a custom-designed high-performance SAW filter revolving around the desired frequency. Each LNA module has an EMI shield to separate the LNA from external interference. Each module has three different power options, but always supply power with one option. Recommended power input from the SMA output port for SDR with Bias T support (such as NESDR SMArTee XTR) is 3V to 5V DC. Or if you do not have a Bias T-enabled SDR, you can use the external power options via a micro USB port or power input header (female 0.1" header). Recommended external power input is 3.3V-5.5V DC. SAWbird has overvoltage protection circuits that work with voltage up to 12V DC and will not damage the device, but is not recommended for long term use. Please note that it will not cause damage due to over-voltage conditions. Covered by a standard 1 year warranty. Please note that some SDR may work with ESD protection diodes by LNA when external power is supplied. Of course, you can use LNA with these SDRs, but if you use a DIY solution to install DC blocks between your LNA and SDR, this is as easy as a high quality capacitor with low distortion connected to the RF path and series.

Review: 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!
Review: It did what it said on the box. I was able to finish my homebuilt telescope and see the hydrogen line!

excellent produit, faible bruit, et bien filtré, ne laisse passer que la bande SHF du H1, pour les radioastronomes, et les amateurs du SETI.
