L/S-Band burst-mode PSK transceiver

com1902 block diagram
KEY FEATURES
  • L/S-band modem to send and receive UDP frames over wireless, satellite or cable. (For continuous-mode see COM-1905)
    • BPSK/QPSK modulation with coherent demodulation
    • Convolutional or turbo-code error correction
    • Nominal frequency of operation: 950 – 2175 MHz for direct connection to external LNB or BUC. Customization to other frequency bands is possible.
    • Burst mode operation:
      • Programmable fixed-length data frames from/to LAN/UDP ports
      • Multiple frames transmitted efficiently with only 37-symbol separation
    • Acquisition: 87-symbol preamble with no apriori knowledge of arrival time
    • Large frequency acquisition range: +/- 20% of symbol rate with no apriori knowledge
    • Programmable symbol rate up to 39.5 MSymbols/s
    • Aluminum enclosure with rubberized end caps. L x W x H: 168.5mm x 138.96 mm x 40.98 mm.
    • Supply voltage: 18 - 36VDC with reverse voltage and surge protection. 5.6V min when no supplying external LNB power.
    • Frequency reference: internal TCXO or input for an external, higher-stability 10 MHz frequency reference
    • Built-in tools: PRBS-11 pseudo-random test sequence, BER tester, AWGN generator, internal loopback mode
    ComScope-enabled: key internal signals can be captured in real-time and displayed on the host computer
