Microwave teeb liab generator

Lub teeb liab generator nyob rau hauv thaj tsam ntawm decimeter yoj mus rau millimeter yoj. Cov teeb liab feem ntau yog tsim los ntawm ultra-high zaus transistors thiab reflective klystrons nrog cov kev faib tsis muaj resonators, tab sis muaj ib qho kev hloov ntawm cov khoom siv hauv lub xeev xws li microwave transistors, field effect transistors, thiab Gunn diodes. Cov cuab yeej feem ntau vam khom cov kab noj hniav kom hloov pauv lawv qhov zaus, txhua lub cuab yeej tuaj yeem npog txog ib qho octave, thiab lub teeb liab fais fab txuas los ntawm kab noj hniav feem ntau tuaj yeem ncav cuag 10 milliwatts. Ib qho yooj yim teeb liab qhov yuav tsum tau tsuas yog 1000 Hz square wave amplitude modulation, thaum tus qauv teeb liab generator tuaj yeem kho cov zis siv qib rau 1 milliwatt, thiab tom qab ntawd nyeem tus nqi decibel milliwatt ntawm cov teeb liab theem tom qab attenuator; Tseem yuav tsum muaj cov kev ntsuas sab hauv lossis sab nraud ntawm lub ntsuas pulse amplitude rau kev kuaj cov receivers xws li radars.
Zaus cheb thiab qhov kev pab cuam tswj lub teeb liab generator
Lub tshuab hluav taws xob zaus cheb teeb liab tuaj yeem tsim lub teeb liab nrog lub amplitude tas li thiab kev hloov pauv hauv cov zaus hauv ib qho kev txwv. Siv cov zaus ntsuas hluav taws xob tsawg lossis tam sim no los tswj cov voj voog oscillation (xws li varactors lossis magnetic core coils) nyob rau hauv lub high-frequency thiab VHF bands kom ua tiav swept zaus oscillation; Nyob rau theem pib ntawm ntu microwave, qhov ntsuas hluav taws xob hloov zaus cheb tau siv los hloov cov zaus oscillation los ntawm kev hloov DC voltage ntawm kauv electrode ntawm lub raj xa rov qab-yoj. Tom qab ntawd, sib nqus tuning zaus cheb tau dav siv, siv YIG ferrite cov khoom ua lub voj voog ntawm lub microwave khoom oscillator, thiab siv cov scanning tam sim no los tswj DC magnetic teb los hloov cov resonance zaus ntawm cov khoom. Lub tshuab hluav taws xob zaus cheb teeb liab muaj qhov tsis siv neeg zaus cheb, tswj phau ntawv, tswj kev pab cuam, thiab cov chaw taws teeb tswj hom kev ua haujlwm.
