Features:1. It is a very low noise, high linearity and low noise amplifier module.2. It has a typical noise ratio of 0.6db, a typical gain of 19dB, 23dB P1dB.3. It can be used for LNA applications with high dynamic range and amplify a small signal of 110dbm.4. You can cascade several LNA modules to improve gain.5. Usually used for high frequency preamplifier or intermediate frequency radio receiver and high sensitivity amplification circuit electronic leak detection device, as well as transceiver wireless communication card, tower mounted amplifier (TMA), coupler, repeaters and distal/digital wireless broadband access, etc. Specifications:Typical Voltage: +5VProject Current: 90mAZisk: 18dB -0.9GImpedance of Input/Output: 50Omega;Max.
