在一般的射頻接受端為了提高接到訊號的訊雜比、或是降低接收到的雜訊，通常會使用差動式低雜訊放大器（LNA）。然而常見的天線都是屬於單端輸出，因此會造成天線與放大器的不匹配。所以本論文主要是將倒F型天線天線與一個單端轉雙端的巴倫器做結合，讓訊號從天線進來後透過巴倫器轉為雙端差動訊號灌入低雜訊放大器。
而因為巴倫器屬於利用電感耦合的被動元件，因此為了提高此巴倫器的Q值，所以本論文採用了國家晶片中心提供的GIPD製程來進行設計，可以有效的提高了巴倫器的Q值及效能。之後再將天線與巴倫器同時整合在GIPD製程上，進行共設計與模擬。
最後成功在GIPD晶片上實現一大小為1.5×0.9 mm2的巴倫器，其植入損耗小於1.7dB、振幅不平衡小於0.9dB、相位不平衡小於5°、共模拒斥比大於23dB。而天線與巴倫器整合於GIPD晶片之後，其操作頻寬也有達到500MHz。

In most of the RF front-end of a receiver, differentially driven low noise amplifier is usually used to increase the signal-to-noise ratio, and at the same time, to reduce the common noise signals. However, most of the antennas are single-ended at the output, thus cause mismatch between the amplifier and the antenna. To alleviate the problem, a balun is attached to the antenna. Therefore, after the antenna receives the signals, the balun converts the single-ended signal to the differential signals directly fed into differential low noise amplifier.
In this thesis, a reversed marchand balun is designed. The balun is a passive component based on inductive coupling. In order to increase the Q-factor of the balun, Glass Integrated Passive Devices (GIPD) technology provided by National Chip Implementation Center was applied. This technology not only improves the Q-factor but also increases the stability of the performance. Finally, we integrated the designed balun with a PIFA (Planar Inverted-F Antenna) on GIPD. Co-design simulation is conducted to evaluate the performance of the balun and PIFA combination.
The size of the balun is 1.5×0.9 mm2. The measurement results demonstrate that the balun achieves less than 1.7dB insertion loss throughout the 10–12 GHz operation bandwidth. The phase and amplitude imbalances are less than 5° and 0.9 dB, respectively. The common-mode rejection ratio is greater than 23dB. The combination of balun and PIFA achieves 500MHz bandwidth.
