4-Channel QAM Modulator

QAM-4 QAM Modulator is mainly used in low-end markets and OEM customers. It aims to provide customers with easy operation, complete function, highly integration and most reasonable price.

    The Modulator can input four-way TS (ASI) and outputs one-way RF signal. After data processing, the four-way TS, without multiplexing, are transferred to QAM Modulator, and are processed with intermediate frequency (four adjacent frequency with intervals of 6 MHz or 8 MHz  and the center frequency is 55MHz), and then combined and up-converted and transferred to TV channels.
