A dual LNA module with an integrated, high-performance SAW filter. Designed for NOAA applications near 137MHz.

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!

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.

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.
