摘要
介绍了一种工作频率为26 GHz的单片微波I-Q型矢量调制器的设计和性能。MMIC芯片尺寸为1.75 mm /spl × 2.1 mm，采用直接载波调制，降低了硬件复杂性和成本。在扫频偏置电压控制下获得了静态星座，并对16正交调幅(QAM)调制进行了论证。基带输入电平为2.5 MSample/s，通过任意波形发生器来演示在26 GHz下工作的10 Mbits/s数据速率发射机。
The design and performance of a monolithic microwave I-Q type vector modulator operating at 26 GHz is presented. The MMIC chip which measures 1.75 mm /spl times/ 2.1 mm, employs direct carrier modulation to reduce hardware complexity and cost. The static constellation was obtained with swept bias voltage control, with this, modulation of 16-quadrature amplitude modulation (QAM) is demonstrated. Baseband input levels were applied at 2.5 MSample/s, by an arbitrary waveform generator to demonstrate a 10 Mbits/s data rate transmitter operating at 26 GHz.
