Features: Low-noise amplifiers generally used as highly-frequency medium-frequency preamplifiers for various types of radio receivers and as amplifier circuit for highly-sensitivity electronic detection equipment. In amplification of weak signal, amplifies own noise on signal interferences may be very serious, so it is hoped to reduce this noise in order to improve signal-to-noise ratios of output. Adopts with excellent electromagnetic shieldings performances. 0.01-4G broadband, with 40dB characteristics. Widely used in broadband receiver system front-end, at same time can be added to input of spectrometer to improve sensitivity to use. Specifications: Operating voltage: +5V single power Operating current: 90mA (low power consumption) Working frequency: 0.01-4GHz : 37dB@1GHz. Output power: 100mW (20dBm) Noise figure: 0.6dB Size: about 53x30.5x14mm/2.08x1.22x0.55in For Spectrum Analyzers Package Includes: 1PC 0.01-4G RF Low Noise Amplifier note: Due to the problem of lighting effect and shooting, there might be tolerances in product, please understand.
