Attenuators Rheoledig Digidol Cam Rheoli Digidol
Mae attenuator rheoledig digidol yn gydran microdon a all reoli'r swm gwanhau trwy signalau digidol.
Ei egwyddor weithredu yw rheoli gwanhau'r signal trwy addasu cyflwr y gydran fewnol neu faint y signal mewnbwn, gan newid y gwerth gwrthiant. O'i gymharu ag attenuators mecanyddol traddodiadol a gwrthyddion amrywiol.
Mae gan attenuators rheoledig digidol y manteision canlynol:
1. Precision uchel: Gall yr attenuator rheoli digidol sicrhau rheolaeth fanwl uchel ar wanhau trwy reolaeth ddigidol, gan gyrraedd cywirdeb o 0.1dB neu lai fel arfer.
2. Band eang: Mae attenuators digidol fel arfer yn gweithredu yn yr ystod GHz neu hyd yn oed THz ac mae ganddynt led band eang.
3. Ystod ddeinamig fawr: Gall yr attenuator cam digidol gyflawni ystod addasadwy o 0dB i 60dB neu fwy, ac mae'r ystod addasu yn eang.
4. Rheolaeth Rhaglenadwy: Gellir rhaglennu'r attenuator rheoli digidol trwy ryngwynebau digidol fel SPI ac I2C, gyda hyblygrwydd uchel.
Defnyddir attenau rheoledig digidol yn bennaf mewn caeau fel profi microdon, radar, cyfathrebu a chyfathrebu lloeren. Gan gymryd y cais prawf fel enghraifft, gellir defnyddio'r attenuator rheoli digidol i addasu pŵer y signal prawf i fesur sensitifrwydd a llinoledd y DUT (dyfais dan brawf); Gellir ei ddefnyddio i raddnodi'r system brofi i sicrhau ei chywirdeb a'i chysondeb; Gellir ei ddefnyddio ar gyfer senarios profi efelychu i werthuso perfformiad gwrth-ymyrraeth y system yn erbyn gwahanol ymyrraeth ac amodau sianel.
EchelinYn cyflenwi band eang ac ystod ddeinamig uchel attenuators rheoledig digidol ar amleddau hyd at 40GHz. Gall y cam fod yn 0.25dB a gall ystod gwanhau fod yn 100dB neu hyd yn oed yn fwy. Mae gan ein attenau rheoledig digidol o ansawdd da a dibynadwyedd uchel, gyda mwy na 70 rhan o rifau, a all ddiwallu anghenion gwahanol gwsmeriaid ac fe'u defnyddir yn helaeth mewn sawl maes.
