MMDS QPSK modulator (DMB-9500) for MMDS broadcasting system, adopts advanced FPGA technology to implement DVB-S channel encoding and QPSK modulation. It fully complys to DVB-S standard and has better IF output performance. The QPSK modulator can be used in the digital satellite television broadcasting system. In addition, it also can be used in MMDS microware point to point transmission system. DMB-9500 MMDS QPSK modulator is the most effective DVB-S modulator in the market.
