L-Band Satellite Receiver 10 Kbps - 2 Mbps

Overview

This receiver is designed for mobile users within L-band satellite coverage. Typical link budget shows reliable transmission at 10 Kbps for users equipped with an omni-directional antenna with only 31 dBW satellite eirp. The guard band between carriers is typically 30% of the modulated bandwidth.

• L-band receiver 1530MHz to 1559MHz, tunable.
• QPSK demodulation for data rates in the range 10 Kbps – 2 Mbps.
• Supplies +5VDC power to an external LNA/ active antenna.
• Input sensitivity: -83 dBm.
  Maximum receiver gain: 105 dB.
• AGC:
  20 dB RF AGC (34 MHz BW)
  20 dB IF AGC (2 MHz BW)
  18 dB Digital AGC.(channel BW)
• Internal TXCO frequency reference accurate to within +/- 2ppm over 0-40C.
  Additional frequency calibration using satellite beacon, accurate to within 1 Hz.
• Turbo product code for error correction:
  7.3 dB coding gain @ 10^-6 BER
  (rate 0.793).
• Support for over-the-air signaling channel.
  Data and signaling streams are multiplexed using HDLC.
• 10 – 32VDC unregulated power supply.
