Taolo ea Leeme ea Ultra Compact IQ Modulator Taolo ea Leeme ea Othomathiki
Tšobotsi
•E fana ka leeme tse tharo bakeng sa li-modulator tsa IQ. Sebopeho sa modification se ikemetse:
•QPSK, QAM, OFDM, SSB e netefalitsoe
• Kenya 'me u bapale:
Ha ho hlokahale tlhahlobo ea letsoho Ntho e 'ngoe le e 'ngoe e iketsahalla
•I, Q matsoho: taolo hodima mekhoa ya Peak le Null Tekanyo e phahameng ya ho fela: 50dB max1
•Letsoho la P: taolo hodima mekhoa ya Q+ le Q- Ho nepahala: ± 2◦
•Boemo bo tlase: 40mm(W) × 28mm(D) × 8mm(H)
•Botsitso bo phahameng: ho kenya tshebetsong ka botlalo ka dijithale Ho bonolo ho e sebedisa:
•Ts'ebetso ea letsoho ka jumper e nyane Ts'ebetso ea OEM e feto-fetohang ka UART2
•Mekhoa e 'meli ea ho fana ka li-voltage tsa leeme: a. Taolo ea Leeme e Iketsang b. Leeme la leeme le hlalositsoeng ke mosebelisi
Kopo
•LiNbO3 le li-modulator tse ling tsa IQ
•QPSK, QAM, OFDM, SSB le jj.
