Nooelec SAWbird NOAA - Premium LNA & SAW Filter Module (137MHz)

Product Overview:

The Nooelec SAWbird NOAA is a high-performance, self-contained Low Noise Amplifier (LNA) and filter module specifically engineered for weather satellite enthusiasts. Optimized for capturing high-quality Automatic Picture Transmission (APT) and Meteor-M2 images, this module targets the 137MHz frequency range. By combining a very low noise figure with high out-of-band attenuation, the SAWbird NOAA isolates sensitive satellite signals from external interference, ensuring superior image clarity even in RF-noisy environments. Housed with an integrated EMI shield, it is a professional-grade tool for optimizing Satellite-to-PC communication via Software Defined Radio (SDR).

Key Features:

This module provides a minimum of 20dB gain centered at 137.5MHz, paired with an ultra-low noise figure of approximately 0.7dB for maximum signal sensitivity. It offers versatile power flexibility with three distinct options: Bias-tee (3V–5V DC via SMA output), microUSB, or a DC barrel header (3.3V–5.5V). With a low current consumption of only 80mA, it is compatible with most standard SDR bias-tee circuits. The hardware includes an EMI shield to protect the sensitive LNA from local interference and standard M3 mounting holes for easy integration into custom enclosures. For safety, the circuitry includes overvoltage protection, though it is optimized for long-term use within the recommended voltage range.
