A Low Noise Amplifier (LNA) ke seholisa se nang le palo e tlase haholo ea lerata. E sebelisoa haholo ho holisa mats'oao a fokolang ha a ntse a fokotsa tšitiso ea lerata ho ntlafatsa karo-karolelano ea mats'oao ho lerata. Hangata e behoa karolong e ka pele ea mochine oa ho amohela seea-le-moea, joalo ka ka mor'a lenakana, ho holisa matšoao a fokolang a tsoang moeeng.
Litšobotsi:
1. Setšoantšo sa Lerata le Tlase: Tšobotsi ea mantlha ea Sehlahisoa sa Lerata le tlaase ke palo ea sona e tlaase haholo ea lerata (Lerata la Lerata, NF). Ha palo ea lerata e le tlase, tšitiso e fokolang ea lerata e hlahisoang ke amplifier, e bakang karo-karolelano e phahameng ea mats'oao ho lerata.
2. Phaello e Phahameng: E le ho matlafatsa matšoao a fokolang ka katleho, "Loll Noise Amplifier" hangata e na le phaello e phahameng, e ka eketsang boholo ba lets'oao.
3.Wide Bandwidth: Li-Amplifaya tse ngata tse tlase tsa Noise Amplifiers li etselitsoe ho ba sephara, tse khonang ho sebetsana le matšoao ho pholletsa le mefuta e mengata ea maqhubu.
4.Botsitso bo Botle: Sehlahisoa se tlaase sa Noise Amplifier se hloka ho ba le botsitso bo botle ho qoba oscillation ha e sebetsa ka maqhubu a phahameng.
Li-Amplifiers tsa Low Noise li sebelisoa haholo puisanong e se nang mohala, puisanong ea sathelaete, radar, methati ea elektronike, bolepi ba linaleli ba seea-le-moea le mafapha a mang.
Qualwave e fana ka mefuta e fapaneng ea li-amplifiers tse tlase ho tloha 4K ho isa ho 260GHz, 'me palo ea lerata e ka ba tlase ho 0.7dB.
Re hlahisa e 'ngoe ea tsona, ka maqhubu a ho tloha 9KHz ho ea 3GHz, phaello ea 43dB, palo ea lerata ea 3dB, P1dB ea 16dBm.
