Manually variable Attenuators suav nrog ob hom khoom:

Rotary Stepped Attenuator thiab Nruam Variable Attenuator.
Rotary Stepped Attenuator yog cov khoom siv hluav taws xob siv los tswj cov teeb liab lub zog. Nws cov yam ntxwv tseem ceeb yog tias nws muaj tus naj npawb ntawm cov kauj ruam attenuation, txhua kauj ruam attenuation yog sib npaug, thiab cov kauj ruam raug yog siab, uas tuaj yeem ua tiav cov teeb liab attenuation yog heev.
Nruam Variable Attenuators yog cov khoom siv hluav taws xob uas tuaj yeem tswj cov teeb liab lub zog tsis tu ncua. Nws lub ntsiab feature yog hais tias nws muaj peev xwm ua tau linear los yog nonlinear teeb liab attenuation los ntawm rotating los yog hloov voltage.

Nta ntawm Rotary Stepped Attenuator:

1. Kauj ruam attenuation: Kho lub attenuation tusyees txhua zaus.
2. High precision: tuaj yeem tswj lub teeb liab lub zog nyob rau hauv ntau yam meej.
3. Loj tag nrho attenuation: tuaj yeem ncav cuag lossis tshaj 90dB attenuation.
4. Tsis tshua muaj suab nrov: suav hais tias yog hom passive attenuator nrog lub suab qis.

Daim ntawv thov txog Rotary Stepped Attenuator:

1. Cov khoom siv suab: siv los kho qhov loj ntawm lub hwj chim amplifier teeb liab tso zis.
2. Cov khoom siv sib txuas lus: siv los kho lub zog ntawm cov teeb liab txais tos kom tsis txhob muaj kev puas tsuaj rau cov khoom siv los ntawm cov teeb liab muaj zog heev.
3. Kev ntsuas ntsuas: siv los kho cov teeb liab lub zog kom tau raws li qhov yuav tsum tau ua.
4. Cov cuab yeej siv hluav taws xob microwave: siv los kho qhov loj thiab siv cov teeb liab microwave.

Nta ntawm Nruam Variable Attenuator:

1. Kev hloov pauv tsis tu ncua: Lub teeb liab lub zog tuaj yeem tswj tau tsis tu ncua hauv qhov ntau.
2. Cov neeg raug siab: muaj peev xwm ua tau zoo heev cov teeb liab attenuation.
3. Cov lus teb ceev ceev: Lub teeb liab teb ceev ceev thiab tuaj yeem hloov kho sai sai rau attenuation.

Daim ntawv thov txog Nruam Variable Attenuator:

1. Kev sib txuas lus wireless: siv los kho lub zog ntawm cov teeb liab txais tos kom tsis txhob muaj kev puas tsuaj rau cov khoom siv los ntawm cov teeb liab muaj zog heev.
2. Cov khoom siv suab thiab yees duab: siv los kho qhov loj thiab lub zog ntawm cov suab thiab cov teeb liab.
3. Kev ntsuas ntsuas: siv los kho cov teeb liab lub zog kom ua tau raws li qhov yuav tsum tau ua.
4. Kav hlau txais xov txais: Siv los kho lub teeb liab lub zog tau txais los ntawm tus kav hlau txais xov los txhim kho kev txais tos zoo.

Qualwavemuab VSWR qis thiab siab attenuation flatness ntawm DC mus rau 40GHz. Lub attenuation ntau yog 0 ~ 121dB, cov kauj ruam attenuation yog 0.1dB, 1dB, 10dB. Thiab qhov nruab nrab lub zog tuav yog mus txog 300 watts.
