KU LNA 750850 A WG, Low Noise Amplifier
7500 … 8500 MHz
The KU LNA 750850 A WG is KUHNE’s newest X-band super low-noise amplifier and was particularly developed for low-noise receive applications, e.g., satellite ground station equipment. Thanks to the combination of an extremely low noise figure, a high gain and high P1dB and IP3, very weak input signals can be amplified with low noise to a power level that is easy to process. The RF input using a WR112 waveguide promises low-loss coupling to the antenna system.
