L4000 are Low Noise Amplifiers with bandpass pre-filtering for outdoor operation.
The LNA features low noise figure, high passband gain, and excellent outband rejection. The series includes models to cover different UHF, L, and S bands.
Typically placed close to a passive antenna, L4000 fixes the system noise figure, improving receiver sensitivity while protecting the next stages against out-of-band interference and jamming.
The amplifiers have a rugged design for operating in harsh environments, including IP67 aluminium enclosure, extended temperature range, and vibration/shock robustness.
