1.This amplifier can work in a wide frequency range with stable gain. When different gain values are needed, the supply voltage can be reduced or customized. With metal shell , which has a noise reduction effect 2.This amplifier's noise figure is 2dB (measured at 1.5GHz), owns smaller noise and larger dynamic range, especially suitable for various RF receiving front‑end circuits, and increase the communication distance 3.WIFI receiver RF front end and other places where low noise and small signal RF amplification is required! Due to its low performance, it can be perfectly matched with various circuits. The product is very thin, very pratical. 4.The product has a wide frequency range, high gain, low noise figure. The low‑noise amplifier module can provide very low noise in a wide frequency range. This can provide a communication effect between the receiver and the mitter 5.Wide range of applications, used for shortwave, FM broadcasting, remote control receivers, cable TV s and other RF signal amplification that require low noise.<br><br>Item Type:RF Wideband Low Noise Amplifier LNA Power Supply Voltage:12V DC (typical current value 75MA) Gain:19.5DB input and output impedance:50 ohms Maximum Output Power:19.5dBm (under 6VPP/50 ohm load) Input Signal:greater than equal 0DBM (the output signal is already distorted when input is greater than 0dBm) Bandwidth:1MHz to 3GHz (gain is different at different frequencies) Noise Figure:2dB (measured at 1.5GHz) With metal shell Others:When different gain values are needed, the power supply voltage can be reduced or customized.
