High speed data transmission at 28 ghz for 5g wireless system / Lo Fang Jenn
Generasi ke-5 sistem tanpa wayar telah menjadi topik paling hangat tahun ini. Mm gelombang adalah salah satu teknologi yang akan melakukan yang paling untuk generasi ke-5 untuk sistem wayarles. Penerokaan ke arah jalur frekuensi mili meter pada sistem wayarles adalah penting untuk mengatasi masalah bekalan jalur lebar wayarles kerana yang tidak dijangka semakin meningkat daripada pengguna mudah alih dan permintaan ke arah data.Pada masa ini, lebih awal daripada generasi ke-4 sistem wayarles kehabisan bandwidth dan akan tepu tidak lama lagi. Kajian daripada 28 GHz mili-meter gelombang transceiver yang diperlukan untuk merealisasikan generasi ke-5 sistem tanpa wayar yang boleh mengatasi masalah bekalan jalur lebar tanpa wayar. Dalam kajian ini, modul sub-sistem yang direka daripada 28 GHz mm gelombang RF depan transceiver dikaji dan diuji. Akhirnya, simulasi dan fabrikasi menyebabkan yang transceiver 28 GHz dibandingkan. Setiap modul sub-sistem RF depan telah dikaji dan diuji menggunakan instrumen microwave seperti PNA-X penganalisis rangkaian, penganalisa isyarat PXA dan disapu penjana isyarat untuk memastikan semua fungsi sub-sistem. Jika apa-apa kerosakan modul sub-sistem dikesan, IC akan diganti. Sekiranya penggantian kad pengenalan baru pada modul sub-sistem tidak functionable, maka reka bentuk baru susun atur litar yang diperlukan. Kedua, kita mengumpulkan seluruh modul subs-sistem bersama-sama untuk membentuk pemancar dan penerima selepas pengesahan telah dijalankan ke atas setiap modul sub-sistem. Kemudian, kita mendapat keputusan eksperimen kuasa output nod sub-sistem setiap transceiver. Lebih-lebih lagi, simulasi itu dilakukan untuk mendapatkan kuasa output nod sub-sistem setiap transceiver 'melalui ADS. Kepincangan modul sub-sistem yang terdapat seperti 28 GHz penguat bunyi yang rendah, penguat kuasa 28 GHz, pengayun terkawal voltan dan kekerapan berganda. Reka bentuk susun atur penguat kuasa 28 GHz dilukis. Akhir kuasa output nod sistem pemancar yang diperolehi adalah 38,439 dBm manakala akhir kuasa output nod sistem penerima yang diperolehi adalah 29,846 dBm dalam simulasi. Secara keseluruhan, modul sub-sistem 28 GHz mm gelombang RF depan transceiver berjaya dikaji dan diuji. Selain itu, simulasi pada transceiver 28 GHz juga berjaya menunjukkan. Yang direka modul subs-sistem 28 GHz transceiver tidak dapat perhimpunan kerana kekurangan komponen. _______________________________________________________________________________________________________ The 5th generation of the wireless system had become the hottest topic for this few years. Mm-wave is one of the technologies that will do the most for 5th generation for the wireless system. The exploration toward milli-meter frequency band on the wireless system is important to counter the shortage of the wireless bandwidth due to the unexpected rising of the mobile users and the demand toward the data. Currently the advance of the 4th generation of wireless system is running out of bandwidth and will be saturated soon. The study of the 28 GHz milli-meter wave of the transceiver is needed to realize the 5th generation of the wireless system that can counter the shortage of the wireless bandwidth. In this research, the fabricated sub-system module of 28 GHz mm-wave RF front-end transceiver is studied and tested. Finally, the simulation and fabrication result the 28 GHz transceiver are compared. Each sub-system module of the RF front-end was studied and tested using the microwave instruments such as PNA-X network analyser, PXA signal analyser and swept signal generator to ensure all the sub-system function. If any malfunction sub-system module was detected, the IC would be replaced. Should the replacement of the new IC on the sub-system module is not functionable, then a new design of the circuit layout is needed. Second, we assembled all the subs-system module together to form transmitter and receiver after verifications were done on each sub-system module. Then, we obtained the experimental result of the output power of each transceivers’ sub-system node. Moreover, the simulation is done to obtain the output power of each transceivers’ sub-system node through ADS. The malfunction sub-system modules are found such as 28 GHz low noise amplifier, 28 GHz power amplifier, voltage-controlled oscillator and frequency multiplier. The layout design of the 28 GHz power amplifier is drawn. The final output node power of the transmitter system obtained is 38.439 dBm whereas the final output node power of the receiver system obtained is 29.846 dBm in simulation. Overall, the sub-system module of 28 GHz mm-wave RF front-end transceiver is successfully studied and tested. Besides that, simulation on the 28 GHz transceiver is also successfully demonstrated. The fabricated subs-system modules of 28 GHz transceiver are not able to assembly due to the lack of components.
