Key Features

 BD-300 - Features

  • Digital Control down converterwith programmable LO frequency 1050~2300MHz

  • The power source can be either

    • from RF cable (+12V)*
    • from USB connector (+5V)
  • Input frequency for 2.4GHz port: 2200~2600MHz (*)
  • Input frequency for 1.2GHz port: 1100~1350MHz(*)
  • 2.4GHz LNA gain: 10dB
  • 1.2GHz LNA Gain: 10dB
  • 2.4GHz Noise Figure: 2dB
  • 1.2 GHz Noise Figure: 1.5dB
  • Pmax: -10 dBm
    • Recommended 2.4GHz < -15 dBm, 1.2GHz < -25 dBm

*Note: when 12V DC power input from the RF-outputport, there is a PWM noise from 0~250MHz while USB connector (+5V) power inputdoes not have this issue. It’s recommended to use USB connector (+5V) powerinput if the target converted channel frequency is < 300MHz.

*Note:

  1. The frequencyrange is only for reference and not limited. Basically full range (950MHz~2.6GHz) is supported, but the pre-AMP LNA’s performance will be degraded inthe band out of the range specified.

  2. The frequencyrange is specified based on >10dB gain for the pre-AMP LNA.

  3. Refer tothe specifications of the pre-AMP LNA Maxim MAX2644 / MAX2691 for further details.
