  • 100kHz-4GHz Wideband, Maximize Portable Test Efficiency: This RF low noise amplifier covers a full frequency range from 100kHz to 4GHz with a typical 20dB flat gain. It effectively pulls weak signals hidden below the noise floor, significantly improving the detection sensitivity of portable SDRs and spectrum analyzers during mobile monitoring
  • Low Power Consumption for Extended Fieldwork: Engineered with a highly efficient power management circuit and a built-in 300mAh battery, this LNA delivers long operation time on a single charge. Its minimal power draw makes it ideal for long-duration outdoor direction finding and field strength surveys where every bit of battery life counts
  • Clean Low-Noise Amplification: Featuring a low noise figure, this module adds minimal background noise during amplification. It ensures a clean, reliable measurement baseline when capturing extremely weak transmissions, preventing the amplifier itself from degrading the received signal quality
  • Universal SMA Connectivity: Equipped with standard SMA female connectors and clear RF IN/OUT markings, the module allows for quick, hassle-free installation. It pairs seamlessly with TinySA Ultra, SDR and professional EMI test instrumentation (Unless specifically requested, please avoid using both the built-in LNA and external LNA of tinySA ULTRA at the same time)
  • Note: It is not recommended to employ a preamplifier in an environment with intense background noise. This might clog the receiver or cause the AGC circuit of the receiver to lower the reception gain. Please note that when testing the LNA, do not apply excessive power or signal, as this may lead to saturation or even damage to the device
