LNA 1350-1450 MHz super low noise

for radio astronomy

The Low Noise Preamplifier (LNA) is the first active component of the receiver chain. It provides the first amplification of the RF signal coming out from feed horn. It is a critical component regarding the overall noise figure (NF) of the receiver, one of most important parameter in radio astronomy. This professional LNA offers all these features in a lightweight, compact body: this is why it is supplied as standard LNA with every SPIDER radio telescope for 1420 MHz detection.

description

When you want to study the weak signals typical of radio astronomy, it is necessary to maximize the incoming waves from space and, at the same time, maintain as greater stability as possible. This professional LNA offers all these features in a lightweight. The LNA 1350-1450 MHz super low noise provides a 33dB gain with a noise figure of only 0.4. It is therefore perfect to amplify very weak radio signals.

It has a F type connector for the coaxial cable. It has has a WR75 flange so if you want to connect it to a Ku-band illuminator with a C120 circular flange, you must use a special adaptor which we sell separately.
