The Advantech‰’s Low Noise Amplifier (LNA) ALNA-C‰™ is a low noise, highly dynamic range amplifier suitable for use in satellite earth station receiver applications where ultra low noise and high reliability are critical, as well as in other systems operating in the frequency range of 3400 to 4200 MHz. The LNA combines low noise with high linearity and wide band. The built-in Interstage Transmit Reject Filter allows the LNA to operate at the input power of ‰-35 dBm in the TX band of 5.8 ‰- 6.75 GHz. The C-band LNA is available with Noise temperature ranging from 25 K to 45 K. With weather proved packaging, the LNA can meet the demands of the installations in severe environmental conditions. The 1:1 and 1:2 redundant system configurations can be provided. They require special Redundancy Kit. The Advantech‰’s LNA provides an industry leading MTBF of over 200,000 hours.
