Chosinthira cha SP32T PIN ndi rauta ya 1-to-32 RF signal ndi chosankha chomwe chimagwiritsa ntchito ma PIN diode kuti chiziwongolera liwiro lapamwamba komanso kudalirika kwambiri. Ndi gawo lofunikira kwambiri mu radar yamakono komanso makina oyesera okha.

Makhalidwe:

1. Kuchuluka kwa njira zotulutsira: njira 32 zotulutsira zimapangitsa kuti zikhale zoyenera kwambiri pamakina omwe amafunikira kulumikiza zinthu zambiri za antenna kapena madoko oyesera.
2. Magwiridwe antchito apamwamba: Ma switch a PIN diode nthawi zambiri amakhala ndi mawonekedwe abwino kwambiri monga kusungulumwa kwakukulu (kuletsa kulankhulana pakati pa ma channel) komanso kutayika kochepa kwa ma insertion (kuchepa kwa chizindikiro podutsa mu switch), ndi ma frequency ogwiritsira ntchito kuyambira mazana a MHz mpaka makumi a GHz.
3. Kusintha mwachangu: Liwiro la kusintha nthawi zambiri limakhala mu mulingo wa microsecond (μs), mofulumira kwambiri kuposa kusintha kwa makina, ndipo limatha kukwaniritsa zofunikira pakusanthula zamagetsi ndi ntchito zina.
4. Mphamvu yayikulu: Poyerekeza ndi ma switch a CMOS kapena GaAs FET, ma switch a PIN diode amatha kuthana ndi mphamvu yayikulu ya RF.
5. Kutalika kwa nthawi yogwira ntchito komanso kudalirika kwakukulu: Kapangidwe ka semiconductor kolimba, palibe ziwalo zosuntha, kutalika kwa nthawi yogwira ntchito kwambiri.

Ntchito:

1. Dongosolo la radar lokhala ndi magawo: Limagwiritsidwa ntchito kusintha ndi kugawa zizindikiro zotumizira/zolandirira pakati pa mayunitsi ambirimbiri a antenna, ndipo ndi chimodzi mwa zinthu zofunika kwambiri pakukwaniritsa kusanthula kwamagetsi kwa beam (kusanthula kwamagetsi).
2. Zipangizo zoyesera zamagetsi zamadoko ambiri (ATE): Mu mzere wopanga kapena labotale, chida choyesera (monga chowunikira maukonde a vector) chimagwiritsidwa ntchito kuyesa zida 32 zosiyanasiyana motsatizana komanso mwachangu (monga zosefera, ma amplifiers, ma antenna, ndi zina zotero) kudzera mu switch ya SP32T, zomwe zimapangitsa kuti mayeso agwire bwino ntchito.
3. Machitidwe olumikizirana ovuta: Amagwiritsidwa ntchito potumiza ma signal ndikusintha zinthu zina.

Qualwaveimapereka ntchito ya SP32T pa 0.4 ~ 18GHz, ndi nthawi yokwanira yosinthira ya 100nS. Timapereka ma switch okhazikika othamanga kwambiri, komanso ma switch osinthidwa malinga ndi zofunikira.
