L-Band Low Noise Amplifier (LNA)


 

Low Noise Amplifiers are specially designed for satellite earth station receiver front ends and other telecommunications applications. Utilizing state-of-the-art HEMT and MMIC technology, these amplifiers have been designed for both fixed and transportable applications.

State-of-the-art HEMT and GaAs MMIC technology

Designed for both fixed and transportable applications

Cryogenic hot/cold load test

 

Single Thread LL-1500 Series L-Band Low Noise Amplifiers are specially designed for satellite earth station receiver front ends and other telecommunications applications. Utilizing state-of-the-art HEMT and MMIC technology, these amplifiers have been designed for both fixed and transportable applications. High performance models are available with noise temperatures as low as 35 K. Noise temperature specifications are guaranteed over the full bandwidth of the LNA.

 

Features

State-of-the-art noise performance

HEMT/MMIC design

Internal regulator

Reverse polarity protection

High reliability

Fault alarm

Options

50 or 60 dB gain

 

Redundant LNA systems minimize system downtime due to LNA failure by providing a spare LNA and an automatic means of switching to the spare upon failure of a primary LNA. A 1:1 system provides one spare LNA for one primary LNA. A 1:2 system provides a spare LNA for either of two primary LNAs. The systems consist of an outdoor plate assembly which mounts at the antenna hub, an indoor control panel and interconnecting control cable.
