Cov Lus Qhia Ua Haujlwm ntawm 1-18GHz Analog Link RF Over Fiber

1-18GHzAnalog Txuas RF Dhau FiberCov Lus Qhia Siv
1-18GHz Analog TxuasRF hla Fibermuaj ib qho electro-optical conversion module, optical fiber, thiab electro-optical conversion module. Siv los hloov cov teeb liab microwave thiab xa lawv mus rau hauv daim ntawv ntawm lub teeb los ntawm optical fibers, nws tuaj yeem txhim kho kev tiv thaiv kev cuam tshuam, yam tsis cuam tshuam rau kev faib tawm ntawm lub teb nrog electromagnetic radiation, thiab zam kev siv cov xov hlau microwave ntev. Simulate RF fiber optic link frequency band los ntawm 1GHz txog 18GHz.
1. Kev Txhais thiab Kev Piav Qhia txogModule xa xov hluav taws xob
(1) RF nyob rau hauv: RF modulation teeb liab input;
(2) Optical output: Optical teeb liab tso zis;
(3) +5V: +5V DC fais fab mov, module ua haujlwm tam sim no <500mA;
(4) -5V: -5V DC fais fab mov, module ua haujlwm tam sim no <500mA;
(5) GND: Kev sib txuas lus fais fab;
2. Kev piav qhia txog lub ntsiab lus ntawmoptical txais module
(1) RF tawm: RF modulation teeb liab tso zis;
(2) Optical hauv: Optical teeb liab input;
(3) +12V: +12V DC fais fab mov, ua haujlwm tam sim no <100mA;
(4) GND: Kev sib txuas ntawm lub zog fais fab;
3. Cov kauj ruam siv 1-18GHz RF Over Fiber
3.1 Lub module kis tau tus mob optical:
(1) Cov teeb liab RF tawm ntawm qhov chaw nres nkoj RF (18G kis tau tus qauv zaus yog 0.1 ~ 18G, fais fab <15dBm);
(2) Txuas ± 5V DC fais fab mov, tam sim no ＜ 500mA;
(3) Siv lub ntsuas fais fab optical los sim seb OUTPUT puas muaj cov zis optical ruaj khov;
3.2 Lub module txais optical:
(1) Txuas lub RF interface rau qhov kawg ntawm kev sim neeg siv;
(2) Txuas + 12V fais fab mov, tam sim no 100mA;
(3) Muab cov teeb liab kho qhov muag ruaj khov tso tawm los ntawm lub module xa mus rau hauv INPUT
