RF Narrowband High Power Amplifiers MM2425P50B

Mtundu wa MM2425P50B ndi chida chowonjezera mphamvu cha narrowband chomwe chimagwira ntchito pakati pa 2.4GHz ndi 2.5GHz ndipo chimapereka mphamvu yosinthasintha yokhala ndi mphamvu yodzaza ya Watts 200. RF narrowband high power amplifier ili ndi mtengo wamba wonyenga wa -60dBc ndi mtengo wa harmonics wa -30dBc, ndipo kapangidwe ka kutayika kobweza kwa amplifier iyi kamatsimikizira kuti mtengo wamba wa -10dB ukhoza kupezeka. Ngati mukufuna deta yabwino yobweza kutayika, chonde funsani gulu lathu. Chowonjezera mphamvu cha narrowband ichi chili ndi mawonekedwe a kukula kochepa, kulemera kopepuka, mphamvu yayikulu, miyeso yolongosoka ndi 170×130×30 mm ndipo kulemera kwake ndi 2.0 kg. Mtundu uwu wa ma amplifier ungagwiritsidwe ntchito pazinthu zomwe zimafunikira kukula ndi kulemera kwa chinthucho. Kuletsa kwa chowonjezera mphamvu cha narrowband ichi ndi 50 Ω yokhala ndi voliyumu yogwirira ntchito ya 28 Volt.

Mars RF ili ndi dipatimenti yakeyake yaukadaulo wa micro-assembly, yomwe imatsimikizira kwambiri kusinthasintha kwa zinthu zathu zamagetsi zamagetsi komanso mphamvu zotulutsa zambiri. Ukadaulo wa micro-assembly ndi kugwiritsa ntchito kwathunthu ukadaulo wa substrate wolumikizirana kwambiri, ukadaulo wa multi-chip component, ukadaulo wa system/subsystem assembly, ukadaulo wa 3D assembly ndi ukadaulo wina wofunikira, kuti asonkhanitse zigawo zosiyanasiyana zazing'ono (ma circuit chips ophatikizidwa ndi zigawo za chips) zomwe zimapanga ma electronic circuits. Ukadaulo wapamwamba wa electronic assembly wa zinthu zamagetsi ...

√ Kugwiritsa Ntchito Bwino Kwambiri ndi Psat 200 Watts wamba

√ Chitetezo chotentha kwambiri

√ Chotenthetsera chakunja chomwe mungasankhe

√ Kapangidwe kakang'ono kokhala ndi kukula kwakukulu 170×130×30mm

√ Kulemera Kopepuka ndi makilogalamu 2.0

1. Kodi kusiyana pakati pa amplifier ya kalasi A ndi amplifier ya kalasi AB ndi kotani?

Kusiyana kumeneku kukutanthauza momwe ma semiconductor a RF amakhalira otsamira. Amplifier ya Class A ipereka kukulitsa kwa mzere kwambiri pamtengo wotsika kwambiri wa DC kupita ku RF efficiency, zomwe zimamasulira mwachindunji kutentha ndi kukula kwa makina a amplifier. Amplifier ya Class AB ndi mgwirizano wa mzere wabwino, magwiridwe antchito apamwamba komanso kukula kochepa.
