Ka LNB（HX-KaLNB）

Model: SP-k-43

Short Description:

The Ka-band LNB mainly includes a receiving channel, a low-noise amplifier, and a local oscillator circuit; it amplifies the low-noise signal of the Ka-band from the satellite and down-converts it to the S/L band. The product has the characteristics of high reliability and small size, and the product is used in satellite ground terminals.

Low noise; high frequency stability; small size; low phase noise; performance indicators have reached the international advanced level.
