•Kugadzikana kwepamusoro: kushandiswa kwedhijitari zvizere Zviri nyore kushandisa:
•Kushanda nemaoko nemini jumper 2
Flexible OEM mashandiro kuburikidza neUART /IO
• Nzira mbiri dzekupa bias voltages: a.Automatic Bias Control b.User defined bias voltage
Application
•LiNbO3 nemamwe DP-IQ modulators
• Coherent Transmission
1Iyo yakanyanya kutsakatika reshiyo inotsamira uye haigone kudarika 1 iyo system modulator yakanyanya kupera reshiyo.
2Kushanda kweUART kunongowanikwa pane imwe vhezheni yemutongi.

1 Polar zvinoenderana nehurongwa RF chiratidzo. Kana pasina chiratidzo cheRF muhurongwa, iyo polar inofanirwa kuve yakanaka. Kana chiratidzo cheRF chine amplitude yakakura kupfuura imwe nhanho, iyo polar inoshanduka kubva kune yakanaka kuita yakaipa. Panguva ino, Null point uye Peak point ichachinjana. Q + poindi uye Q- poindi inochinja pamwe chete. Polar switch inogonesa mushandisi kuchinja iyo
polar zvakananga pasina kushandura nzvimbo dzekushanda.
