Home » FAQ » Modulators/Demodulators


Our products utilize ASIC and FPGA modulator and demodulator designs, and support BPSK, QPSK, OQPSK, 8-PSK, 8-QAM, 16-QAM, 64-QAM, DVB-S2, 16-APSK and 32-APSK. Depending on the modem, demodulation is accomplished by either frequency conversion down to an intermediate frequency or directly down to base band with over sampling employed. Filtering is accomplished either by switched analog filters or digitally with polyphase FIR filters in the conversion FPGA. Due to the all-digital implementation with polyphase filters, designs are readily transferred to other data rates. Our modulation and demodulation technologies operate as low as 2.4 kbps to over 238 Mbps.
