AURSINC ZK05-BM Low Noise Amplifier 100kHz-6GHz, 24dB Gain LNA Preamplifier

Features

• 100kHz-6GHz Wideband Gain, Boost Weak Signal Sensitivity: This RF low noise amplifier covers a full frequency range from 100kHz to 6GHz with flat and stable gain (24dB typical @10MHz, 21.5dB @1GHz). It effectively amplifies faint RF signals hidden below the noise floor, greatly extending the detection limit of your spectrum analyzer and SDR receiver
• Low Noise Figure with Clean Noise Floor: Featuring a noise figure as low as 0.6dB@1GHz, this LNA adds minimal extra noise during signal amplification. Its built-in high PSRR LDO regulator effectively suppresses power supply noise, delivering a much cleaner measurement baseline and more accurate results than standard direct USB-powered LNA modules
• Built-in Rechargeable Battery for On-the-Go Use: With an integrated 300mAh battery and Type-C charging port, this broadband preamplifier delivers up to 12 hours of continuous operation on a full charge. No external power adapter is required during outdoor field testing, making it ideal for portable EMI detection, radio direction finding and field spectrum analysis
• High Linearity Design, Low Signal Distortion: Boasting a high output IP3 of up to 25dBm@1GHz and high OP1dB of 18dBm@1GHz, the module maintains excellent linearity and avoids intermodulation distortion even with moderate input signals. It serves as a reliable drop-in replacement for TQP3M9035, QPL9058, TQP3M9037 and QPL9547 amplifier modules
• Plug-and-Play, Broad Device Compatibility: Equipped with standard SMA female connectors and clear RF IN/OUT markings, the LNA is easy to install and operate. It works seamlessly with TinySA / TinySA Ultra spectrum analyzers, software defined radios (SDR), ham radio receivers and professional EMI test setups, suitable for both hobbyists and RF engineers
