RF High Switching Speed ​​High Isolation Test Systems SP12T PIN Diode Switches

Ma pin diode nthawi zambiri amagwiritsidwa ntchito ngati masiwichi osinthira pamtengo umodzi wokha. Pin diode imagwira ntchito ngati choletsa kuwongolera kwa ma siginecha okhala ndi ma frequency akulu kuposa nthawi 10 diode cutoff frequency (fc). Powonjezera kutsogolo kwa tsankho, kukana kwa Rj kwa diode ya PIN kumatha kusintha kuchokera kukana kwambiri mpaka kutsika kochepa. Kuphatikiza apo, diode ya PIN itha kugwiritsidwa ntchito pazosintha zonse ziwiri ndikusintha kofananira.

Pin diode imagwira ntchito ngati ma elekitironi owongolera pawailesi ndi ma microwave. Itha kupereka mzere wabwino kwambiri ndipo itha kugwiritsidwa ntchito pafupipafupi komanso pamapulogalamu apamwamba kwambiri. Kuipa kwake ndi kuchuluka kwa mphamvu za DC zomwe zimafunikira kukondera, zomwe zimapangitsa kuti zikhale zovuta kuwonetsetsa kuti kachitidwe kodzipatula komanso kufunikira kokonzekera bwino kuti mukwaniritse bwino. Kupititsa patsogolo kudzipatula kwa PIN diode imodzi, ma PIN diode awiri kapena kuposerapo angagwiritsidwe ntchito pazotsatira. Kulumikizana kwa mndandandawu kumakupatsani mwayi wogawana zomwe zilipo kuti musunge mphamvu.

Kusintha kwa SP12T PIN Diode ndi chipangizo chomwe chimatumiza ma siginecha apamwamba kwambiri a RF kudzera munjira zingapo zopatsirana, potero zimakwaniritsa kutumiza ndikusintha ma siginecha a microwave. Chiwerengero cha mitu yopatsirana pakati pa mzati umodzi woponya khumi ndi iwiri ndi chimodzi, ndipo kuchuluka kwa mitu yopatsirana mubwalo lakunja ndi khumi ndi awiri.

Kusintha kwa SP12T PIN Diode kumagwiritsidwa ntchito kwambiri m'makina osiyanasiyana a ma microwave, makina oyesera okha, ma radar ndi malo olumikizirana, ndipo amagwiritsidwa ntchito kwambiri pakuwunikiranso zamagetsi, zoyeserera, ma radar ambiri, ma radar apakati, ndi magawo ena. Chifukwa chake, kuphunzira masiwichi a microwave ndikutayika pang'ono, kudzipatula kwambiri, burodibandi, miniaturization, ndi njira zingapo kuli ndi tanthauzo laukadaulo.
