Nooelec SAWbird+ 2m Barebones - Premium Dual Ultra-Low Noise Amplifier (LNA) & SAW Filter Module for 2-Meter Amateur Radio Band Applications. 145MHz Center Frequency

• SAWbird+ 2m is a self-contained LNA module designed for 2-meter ham band applications
• The module uses 2 ultra-low-noise LNAs and a custom high-performance SAW filter centered at the frequency of 145MHz (142-148MHz)
• SAWbird+ 2m can be powered in 3 ways: via bias tee (with a current capability of 200mA or higher), through the on-board microUSB connector, or through the on-board female header
• Though compatible with most SDRs, we recommend using the module in conjunction with NESDR SMArTee (available on Amazon, product ID B079C4S2BT)
• Full 1 year support & service directly through Nooelec!

FOR FULL SPECIFICATIONS AND DETAILS, PLEASE REVIEW THE PRODUCT PAGE AT NOOELEC.COM SAWbird+ 2m is a self-contained LNA module designed for operating within the 2-meter band. It has a very high attenuation outside of its 6MHz passband (142-148MHz), centered around 145MHz, with a nominal gain of 40dB within the passband and a nominal current draw of ~200mA. SAWbird+ 2m contains 2 ultra-low-noise LNAs sandwiched around a custom-designed, high-performance SAW filter centered at the frequency of interest. The SAWbird+ 2m has an EMI shield to isolate the internals 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 SAWbird+ 2m 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.
