Ampilifaya Ariwo Kekere, Igbohunsafẹfẹ 9KHz~3GHz, Gain 43dB, Noise Figure 3dB, P1dB 16dBm

Ampilifaya Noise Low (LNA) jẹ ampilifaya pẹlu eeya ariwo kekere ti o kere pupọ. O jẹ lilo ni akọkọ lati mu awọn ifihan agbara lagbara pọ si lakoko ti o dinku kikọlu ariwo lati mu iwọn ifihan-si-ariwo dara si. O maa n gbe ni iwaju opin ti ẹrọ olugba redio, gẹgẹbi lẹhin eriali, lati mu awọn ifihan agbara lagbara ti o gba lati afẹfẹ.
Awọn abuda:
1.Low Noise Figure: Awọn abuda mojuto ti a Low Noise Amplifier ni awọn oniwe-lailopinpin ariwo ariwo (Noise Figure, NF). Isalẹ nọmba ariwo, kikọlu ariwo ti o dinku ti ampiliffitafita ṣafihan, ti o mu abajade ifihan-si-ariwo ti o ga julọ.
2.High Gain: Lati le ṣe imunadoko awọn ifihan agbara alailagbara, Low Noise Amplifier ni igbagbogbo ni ere giga, eyiti o le ṣe alekun titobi ifihan agbara naa.
3.Wide Bandwidth: Ọpọlọpọ Awọn Amplifiers Noise Low ti ṣe apẹrẹ lati jẹ jakejado, ti o lagbara lati mu awọn ifihan agbara mu kọja iwọn igbohunsafẹfẹ gbooro.
4.Good Stability: Ampilifaya Noise kekere nilo lati ni iduroṣinṣin to dara lati yago fun oscillation nigbati o nṣiṣẹ ni awọn igbohunsafẹfẹ giga.
