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.
