Ka-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

 

WIDEBAND FEATURES

LKKC-20120 Ka-Band Ultra Low Noise Amplifier is specially designed for satellite earth station and other telecommunications applications. Utilizing state-of-the-art HEMT and GaAs MMIC technology, this amplifier has been designed for both fixed and transportable applications. The noise temperature specification is guaranteed over the full bandwidth of the LNA, and measured using a cryogenic hot/cold load test setup.

Options

Low gain, 50 dB typical

High Output power, P1 dB = +20 dBm minimum

Excellent guaranteed gain stability due to built-in temperature compensation circuit (test data provided)

Universal input AC power supply

 

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.
