Umenzi we-VHF Bandpass filter yesisombululo seTetra
Umenzi we-VHF Bandpass filter yesisombululo seTetra,
Umyili wesihluzi seRF,
Inkcazo
I-VHF Bandpass Lumped Component Filter Esebenzayo ukusuka kwi-155-245MHz
I-VHF band pass LC filter JX-LCF1-155M245M-S20 iyilwe kwaye iveliswe nguJingxin. I-frequency yayo igubungela ukusuka kwi-155-245MHz kunye nebhendi yokupasa ye-90MHz, ebonisa ilahleko yokufaka engaphantsi kwe-1.5dB, ilahleko yokubuyisela ngaphezulu kwe-14dB, i-ripple engaphantsi kwe-0.4dB, ukwaliwa ngaphezulu kwe-20dBc@DC-40MHz & 320-480MHz,60dBc00000000Mhz . Ilinganisa i-40.4mm x 12mm x 10mm ngevolumu encinci, iyafumaneka kunye nezixhumi ze-SMA, ipeyintwe ngombala omnyama ubomi obude.
Njengomyili we-LC yesihluzi, uhlobo olunjalo lwesihluzi secandelo le-VHF luninzi kwikhathalogu ye-Jingxin, i-Jingxin inokukunceda kuyo nayiphi na ingxaki ye-RF yokungenzi nto. Yenza njengesithembiso, onke amacandelo e-RF avela kwi-Jingxin anewaranti yeminyaka emi-3.
