LOW NOISE BLOCK DOWN CONVERTER

• xhe receiver uses Low Noise Block Down Converters (C or Ku-Band LNB) for its microwave interface. The output frequency

range is 950 to 1450MH2. Power is supplied to the LNB via its output F connector.

Note:

The receiver is capable of supplying 18 V DC at 300 milliamps max from the input F connector.

• This is sufficient for one LNB and one Line Amplifier. The breakdown is shown below.

Line Amp (+20 dB)

100 milliamps max

LNB

200 milliamps max

If the line amp used only 25 milliamps, then four line amps can be used.
