1. [Operating frequency] This RF low noise amplifier LNA is 50-4000MHz, = 0.6dB 2. [Application] It is commonly used as a high frequency or intermediate frequency preamplifier for various radio receivers, as as an amplifying circuit for high sensitivity electronic detection equipment 3. [Wide range] This LNA for primary mobile communications station infrastructure applications such as wireless communication transceiver cards, tower amplifiers, combiners, repeaters and remote/digital wireless broadband terminal applications 4.LNA RF Amplifier] This is an LNA RF amplifier with a low noise figure produces lower noise and distortion while amplifying the signal 5.[ 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 output Ultra-low Noise Figure = 0.60 db at 900MHZ Gain = 18.7db at 900MHZ High Linearity: OIP3 39.5dbm at 1960 MHZ P1db = 22.7dbm at 1960 MHZ Single-supply Operation: 5V at IDO = 90MA Flexible Biasing : 3V to 5V, Adjustable Currents Broadband Internal Matching Cellular, PCS, W-CDMA, WIMAX Receivers PA Driver Amplifier Low Noise, High Linearity Gain Block Applications Colour:green Material:PCB+metal Size:5 x 2.5 x 1cm Package Contents: 1 x RF Amplifier Only the above package content, other products are not included.
