QPSK dvb-c rf modulator for wireless MMDS system
Outline
The COL5500 QPSK modulator is a high performance modulator developed according to DVB-S (ETS300-4221) QPSK standard. It has powerful spectral efficiency, advanced anti-jamming and competitive price-performance ratio. Apart from these, this modulator also has access to FM microwave device. Moreover, to guarantee the high transmission performance, this QPSK modulator adopts the disposal of energy diffusing, RS coding, convolution interlacing and pre-modulated baseband shaping. To sum up, all the approaches make this QPSK modulator can be widely used in Broadcasting, Interactive Services, News Gathering and other Broadband satellite applications.
