This low noise amplifier module is used as a high frequency or intermediate frequency preamplifier for UHF and VHF band radio receivers, as well as an amplification circuit for highly sensitive electronic detection equipment. Low noise amplification: This amplifier is designed to minimize noise and provides clear and powerful signal enhancement without adding unnecessary interference, making it suitable for critical communications and spectrum analysis. Features a low noise LNA core with a low-end frequency down to 10 kHz. Housed in a CNC-machined metal enclosure for excellent electromagnetic shielding. 40 dB high gain with high gain flatness, widely used in the front end of broadband receiver systems; can also be connected to the input of a spectrum analyzer to improve sensitivity. Operating voltage: +5 V DC (single supply). Operating current: 75 mA. Frequency range: 1 MHz to 1.5 GHz. Typical gain: 40 dB (see test curve). P1dB output power: +4 dBm. Noise figure: 2.4 dB. Input/output connector: SMA (female jack, male plug). Color: As shown. Material: CNC-machined aluminum. Due to manufacturing variations, minor differences in appearance and labeling may occur; these do not affect performance or functionality. Package includes: 1 × RF Low Noise LNA Amplifier. Note: Color appearance may vary slightly due to lighting conditions and screen settings. Dimensions are subject to a tolerance of ±1–3 cm.
