Re: DEM 13LNA Preamp



Regarding your concern that the amplifier is rated at 0.7 dB noise figure,
a bit higher than the device noise figure, 

"The noise figure of the completed amplifier is equal ot the noise figure
of the device plus the losses of the matching network preceding the
device"

This phrase happens to be from an Agilent data sheet for the ATF-54143,
but applies to any device.  Beware specsmanship!
