ʻO Ultra Compact IQ Modulator Bias Controller Automatic Bias Controller
Hiʻona
• Hāʻawi i ʻekolu manaʻo no ka IQ modulators Modulation format kūʻokoʻa:
•QPSK, QAM, OFDM, SSB hōʻoia
• Hoʻopili a pāʻani:
ʻAʻole pono ka calibration manual
• Nā lima I, Q: hoʻomalu i nā ʻano Peak a me Null Lakiō hoʻopau kiʻekiʻe: 50dB max1
•P lima: ka hoomalu ana ma Q+ a me Q- Ka pololei: ± 2◦
•Kuhi haʻahaʻa: 40mm(W) × 28mm(D) × 8mm(H)
• Paʻa kiʻekiʻe: hoʻokō kikohoʻe piha Maʻalahi e hoʻohana:
• Ka hana lima me ka mini jumper Hoʻololi OEM hana ma o UART2
• ʻElua mau ʻano no ka hāʻawi ʻana i nā volt bias: a.Automatic Bias Control b.User definition bias voltage
Palapala noi
•LiNbO3 a me nā mea IQmodulators ʻē aʻe
•QPSK, QAM, OFDM, SSB a pela aku
•Ka Hoʻouna Kūlike
