ʻO ka Low Noise Amplifier (LNA) he amplifier me kahi helu walaʻau haʻahaʻa loa. Hoʻohana nui ʻia ia e hoʻonui i nā hōʻailona nāwaliwali me ka hoʻēmi ʻana i ka hoʻopilikia walaʻau e hoʻomaikaʻi i ka ratio signal-to-noise. Hoʻonoho pinepine ʻia ia ma ka ʻaoʻao mua o kahi ʻōnaehana hoʻokipa lekiō, e like me ma hope o ka antenna, e hoʻonui i nā hōʻailona nāwaliwali i loaʻa mai ka lewa.
Nā ʻano:
1. Kiʻi Walaʻau Haʻahaʻa: ʻO ke ʻano koʻikoʻi o kahi Hoʻonui Walaʻau Haʻahaʻa ʻo ia kona kiʻi walaʻau haʻahaʻa loa (Kiʻi Walaʻau, NF). ʻO ka haʻahaʻa o ka kiʻi walaʻau, ʻo ka emi ʻana o ka hoʻopilikia walaʻau a ka amplifier e hoʻokomo ai, e hopena ana i kahi lakio signal-to-noise kiʻekiʻe.
2. Loaʻa Kiʻekiʻe: I mea e hoʻonui pono ai i nā hōʻailona nāwaliwali, loaʻa i kahi Hoʻonui Walaʻau Haʻahaʻa kahi loaʻa kiʻekiʻe, hiki ke hoʻonui nui i ka amplitude o ka hōʻailona.
3. Wide Bandwidth: Ua hoʻolālā ʻia nā mea hoʻonui walaʻau haʻahaʻa he nui e lilo i wideband, hiki ke lawelawe i nā hōʻailona ma kahi laulā alapine ākea.
4. Paʻa Maikaʻi: Pono ka mea hoʻonui walaʻau haʻahaʻa i ke kūpaʻa maikaʻi e pale aku ai i ka oscillation i ka wā e hana ana ma nā alapine kiʻekiʻe.
Hoʻohana nui ʻia nā mea hoʻonui walaʻau haʻahaʻa i ke kamaʻilio uea ʻole, ke kamaʻilio ukali, ka radar, nā countermeasures uila, ka astronomy radio, a me nā ʻoihana ʻē aʻe.
Hāʻawi ʻo Qualwave i nā ʻano mea hoʻoikaika leo haʻahaʻa mai 4K a 260GHz, a hiki ke haʻahaʻa ka helu walaʻau e like me 0.7dB.
Ke hoʻolauna nei mākou i kekahi o lākou, me nā alapine (frequencies) mai 9KHz a i 3GHz, kahi loaʻa o 43dB, kahi helu walaʻau o 3dB, kahi P1dB o 16dBm.

Ua hōʻiliʻili ʻo Qualwave i nā makahiki o ka ʻike ma ka noiʻi a me ka hoʻomohala ʻana i nā mea hoʻoikaika leo haʻahaʻa, hiki ke hoʻokō i ka hana nui a me ka noiʻi a me ka hoʻomohala maʻamau e like me nā pono o ka mea kūʻai aku.
Welina mai e waiho i kahi leka no ka ʻike hou aku.
