摘要

我们开发了一种用于Ka波段卫星通信的直接线性矢量调制器MMIC。该调制器为并行I/Q型，包括用于校正正交相位误差的片上相位调谐。利用调谐的可能性，获得了良好的调制效果。这是QPSK操作的说明，其中在20%宽的RF带宽中获得准完美调制，完全覆盖国际电联分配的FSS(固定卫星业务)Ka波段下行频率。

A subharmonically pumped I/Q vector modulator MMIC for Ka band satellite communication

We have developed a direct linear vector modulator MMIC for Ka band satellite communication. The modulator is of the parallel I/Q type and includes on-chip phase tuning for correcting the quadrature phase error. Using the tuning possibilities, excellent modulation results are obtained. This is illustrated for QPSK operation where quasi-perfect modulation is obtained in a 20% wide RF bandwidth, completely covering the FSS (Fixed-Satellite Service) Ka band downlink frequencies as allocated by the ITU.
