Features: brand new and high quality This is a ultra low noise, high linearity, low noise amplifier module. It has 0.6dB typical noise factor, 19dB typical gain, 23dB P1dB. Widely be used for high dynamic range receiver LNA application, and amplify small signal of 110dBM. It can be cascaded several LNA modules in order to improve gain. Used for high frequency or intermediate frequency preamplifier of radio receiver, and high sensitivity amplifying circuit of electronic detection equipment, as well as transceiver wireless communication card, tower mounted amplifier (TMA), combiner, repeaters, and distal/digital wireless broadband for head equipment, etc. Specifications: Typical Voltage: +5V Typical Current: 90mA Gain: 18dB -0.9G Input/Output Impedance: 50Ω Max. Output Power: P1db 22dBm(2GHz) Input Signal: <+10dbm(as low="" as="" -110dbm.="" if="" input="">+10dBm, output is distorted) Bandwidth 0.05-4GHZ(differs at different frequency, refers to S21 curve) Noise Factor: 0.6dB-0.9GHz Weight: 40g(approx.) Package Includes: 1 x LNA Low Noise Amplifier 50M~4Ghz note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
