B7 20W RF Power Amplifier Module yokhala ndi LNA

M'njira zamakono zoyankhulirana ndi zida zawayilesi, magetsi ndi kuwunika kwa zida kumakhala ngati zinthu zofunika kwambiri kuti makinawa azigwira ntchito mosasunthika. Module ya amplifier ya 20W RF idapangidwa mwaluso kuti ikwaniritse izi, ndikupereka yankho logwira mtima komanso lodalirika. Module iyi ili ndi mitundu yosiyanasiyana yolumikizirana komanso kuyang'anira kopitilira muyeso, kuwonetsetsa kuwongolera mbali zonse za zida ndi mayankho ake munthawi yake.

Mphamvu yokulitsa mphamvu ya mpanda wamagetsi imakhala ndi mawonekedwe owoneka bwino, kuphatikiza ma RS485A, RS485B, GND, NC, ndi DC+28V zikhomo, zomwe zimatsimikizira kukhazikika kwamagetsi komanso kudalirika kwa kutumiza kwa data. Kuphatikiza apo, gawo la 20W RF power amplifier lili ndi cholumikizira chimodzi cha SMA-50KFD ndi zolumikizira zisanu za MCX, zopangira doko la PA_OUT ndi PA_IN, LNA_OUT, ndi LNA_IN motsatana, zomwe zimathandizira kulumikizidwa kwa zida zosiyanasiyana.

Kuwunika kwake kumakhala kochititsa chidwi, kumathandizira kutsika kwa PA ndi kumtunda kwa LNA kuyang'anira, ndi mlingo wa baud kufika ku 9600, potero kuonetsetsa kuti deta ikutumizidwa mofulumira komanso molondola.

Pankhani ya kuthekera kowunika, gawo la amplifier lamagetsi limapereka ntchito zowunikira zonse za PA ndi LNA. Ogwiritsa ntchito amatha kukhazikitsa adilesi ya module, yambitsani LNA, kusintha ATT, ndikufunsa momwe chipangizocho chikugwirira ntchito munthawi yeniyeni, kuphatikiza mphamvu zambiri, kutentha kwambiri, VSWR, ndi ATT. Mutuwu umakhalanso ndi alamu yomwe imayambitsa alamu yotentha kwambiri ndipo imatseka PA pamene kutentha kumapitirira + 85ºC, ndikuyatsa PA pamene kutentha kumatsikira ku +65ºC. Kuphatikiza apo, imayambitsa alamu yamphamvu kwambiri mphamvu ikatuluka iposa Po+2dB. Kuphatikiza apo, gawo lamagetsi limathandizira kuzindikira kwamphamvu kwamphamvu ya PA reverse mphamvu, kutentha kwa amplifier, VSWR, ndi PA mphamvu yakutsogolo, kuwonetsetsa kuti chipangizocho chimagwira ntchito nthawi zonse.

Mwachidule, amplifier yamagetsi yamagetsi yakhala ngati njira yabwino yopangira magetsi komanso kuyang'anira zida chifukwa champhamvu zake, magwiridwe antchito odalirika, mawonekedwe apamwamba kwambiri, ntchito zowunikira bwino, komanso makina a alamu oyenerera, kuwonetsetsa kuti dongosololi likugwira ntchito moyenera komanso kukonza nthawi yake. .
