Features: This is a ultra low noise, high linearity low noise amplifier module. It has 0.6dB typical noise factor, 19dB typical gain, 23dB P1dB. Can be used for high dynamic range receiver LNA application, and amplify small signal of 110dBM. You can cascade several LNA modules in order to improve gain. Generallyused for high frequency or intermediate frequency preamplifier of radioreceiver, 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 head equipment, etc. Specifications: Typical Current: 90mA Gain: 18dB@0.9G Input/Output Impedance: 50 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@0.9GHzWeight: 40g(approx.)Package Includes: 1 x LNA .
