1. [Operating frequency] This RF low noise amplifier LNA is 50-4000MHz, = 0.6dB2. [Application] It is commonly used as a high frequency or intermediate frequency preamplifier for radio receivers, as as an amplifying circuit for high sensitivity electronic detection equipment3. [Wide use range] This LNA for primary mobile communications base station infrastructure applications such as wireless communication transceiver cards, tower amplifiers, combiners, repeaters and remote/digital wireless broadband terminal applications4.LNA RF Amplifier] This is an LNA RF amplifier with a low noise that produces lower noise and distortion while amplifying the signal5.[ the signal-to-noise ] In the case of amplifying a weak signal, the noise of the amplifier itself may be very severe, so it is desirable to reduce this noise to the signal-to-noise of the outputUltra-low Noise = 0.60 db at 900MHZGain = 18.7db at 900MHZHigh Linearity: OIP3 39.5dbm at 1960 MHZP1db = 22.7dbm at 1960 MHZSingle-supply Operation: 5V at IDO = 90MAFlexible Biasing : 3V to 5V, Adjustable CurrentsBroadband Internal MatchingCellular, PCS, W-CDMA, WIMAX ReceiversPA Driver AmplifierLow Noise, High Linearity Gain Block ApplicationsColour:greenMaterial:PCB+metalSize:5 x 2.5 x 1cmPackage Contents:1 x RF AmplifierOnly the above package content, other are not included.Note: Light and different displays may cause the color of the item in the a little different from the real thing.
