Features: brand new and high quality It can be cascaded several LNA modules in order to improve gain. It has 0.6dB typical noise factor, 19dB typical gain, 23dB P1dB. This is a ultra low noise, high linearity, low noise amplifier module. 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, combiner, repeaters, and distal/digital wireless broadband for head equipment, etc. Widely be used for high dynamic range receiver LNA application, and amplify small signal of 110dBM. Specifications: Voltage: 5V Current: 90mA Gain: 18dB AT 0.9G Input/Output Impedance: 50Ω Max. Output Power: P1db 22dBm(AT 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 AT 0.9GHz Size:6x2.4cm/2.36x0.94inch Package Includes: 1xRF Amplifier note: Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.
