[2.3 - 2.8 GHz] & [1.15 - 1.4GHz] Receiver
  • [2.3 - 2.8 GHz] receiver[1], software selectable. Designed for use in the 2.3GHz SDARS band, in the 2.4 GHz unlicensed band and in the Multichannel Multipoint Distribution Service (MMDS) band
  • Sensitivity: -51 dBm RF input for full scale 10-bit output samples
  • Built-in RF AGC, 70 dB dynamic range
  • Low-noise frequency synthesizer can be tuned over entire range by steps of 1 MHz, 200 KHz or 100 KHz
  • 8 preset frequencies for fast (<6ms) local oscillator frequency tuning
  • Automatic selection of internal / external 10 MHz frequency reference for the frequency synthesizer
  • Optional operation over extended frequency range [800 MHz - 2.8 GHz] by supplying an externally-generated RF carrier for frequency down-conversion via SMA connector
  • True PLL: multiple COM-3007s can be phase locked onto the same external 10 MHz frequency reference. The LO phase difference among the multiple modules is fixed at power-up
  • Dual 10-bit Analog-to-Digital converters, 40 Msamples/s
  • User-selectable variable (105 Msamples/s max) ADC sampling rate when using external clock or fixed 40 Msamples/s internal clock
  • Multiple receivers can be synchronized in terms of (a) the ADC sampling rate, and (b) the synthesized RF carrier phase by using external frequency references:
    • External ADC sampling clock
    • External 10 MHz RF frequency synthesizer PLL reference
  • Two baseband filtering options:
    • Narrow-band (<300 KHz)
    • Wideband applications (<26 MHz)
  • SMA connectors. Single 5V supply. Connectorized 3”x 3” module for ease of prototyping
