Features: brand new and high quality Application: LNA for the main mobile communication base station infrastructure applications, such as wireless communication transceiver card, tower mounted amplifier (Tma), combiner, Repeaters, and distal/digital wireless wide band end equipment application design. Generally used as a high frequency or intermediate frequency preamplifier for a wide range of radio receivers, as well as amplifying circuits of highly sensitive electronic detection devices. In the for case of amplifying weak signal, the noise of the amplifier itself may be very serious, so it is hoped that this noise will be reduced to improve the signal-to-noise ratio of the output. The amplifier is 5 - 6000MHz (20dB) amplifier, with a wide dynamic range, wide operating frequency range of characteristics. This RF Amplifier features low noise figure, is a LNA RF Amplifier. Specifications: Operating frequency: 5 - 6000MHz Amplifier gain: 20dB Maximum output power: + 21dBm (100mW) @ 1dB compression point Operating Current: 85mA (5V) Supply voltage: 5VDC System impedance: 50 ohms Color: green Size: approx. 25x15mm/0.98x0.59in Material: Electronic component Package Includes: 1 x Amplifier Board note: Due to the difference between different monitors, the picture may not reflect the actual color of the item.
