Compact and slim space-saving design! QPSK modem unit.
The "QM03A" is a dedicated line modem unit that complies with ITU-T Recommendation V.22, utilizing a QPSK (Quadrature Phase Shift Keying) method with a two-wire full-duplex design. The modulation and demodulation core is implemented using FPGA without dedicated LSI, reducing the risk of discontinuation. Additionally, it is a completely newly designed product manufactured domestically, and it is RoHS compliant. 【Features】 ■ Two-wire full-duplex synchronous communication modem ■ Compact and slim space-saving design ■ Loopback diagnostics for both the local unit and the opposing device during communication connections ■ Built-in self-test function capable of conducting error rate tests for the modem, including the line *For more details, please refer to the PDF document or feel free to contact us.
